One-Click Double Order
The shopper ticks once at checkout, and the whole cart comes again — every line doubled, at a discount.
Built for WordPress · WooCommerce
A LUMÉ demo store, on its checkout page — step two of three. The left column is a billing form whose eight labels are drawn from the WooCommerce classic checkout’s own, and under it, in a block of its own, an order-notes field; all nine values are drawn as grey bars, so no name, no address, no phone number and no email address appears. On the right, a panel headed Your order holds a Product and Subtotal head and two lines: a Classic White Tee, Size M, quantity two, at $36.00, and a Zip Hoodie, quantity one, at $54.00. Under them the Subtotal reads $90.00 and the Total reads the same $90.00 — there is no shipping line and nothing has been discounted yet, so nothing separates the two; the masthead reads Order $90.00 and the cart badge reads 3, because it counts units rather than lines. Under the Total two payment rows are drawn with blank grey labels; and below them, between the payment block and the Place order button, where 8theme’s own frontend screenshot puts it, sits the card this page draws for SalesMax: a badge reading Best offer over its corner, and a dashed box holding one unticked checkbox labelled “Click here to double your order and get a 10% discount!”. Then a Place order button. A pointer crosses in from the lower right, rises to the badge and holds there, then drops to the checkbox and presses it once. The box fills and both lines double where they stand, each at its own full price: the tee goes to quantity four, Size M, at $72.00, and the hoodie to quantity two at $108.00. The Subtotal rolls to $180.00, a Discount row appears beneath it reading minus $18.00, and the Total lands at $162.00; the masthead follows the Total, never the Subtotal, and the badge steps from 3 to 6. The right-hand figure moves from $90 to $162, and a pill reads plus $72 — what the doubling adds once its discount is off. One line to a product, and the ten percent taken once in a row of its own rather than priced into the lines, is this page’s own depiction; where a real order prints that discount, nothing published says. The pointer travels up to the Discount row and rests there, then slides down to the Total and holds while it lands. Nothing navigates, nothing overlays the page and nothing enters any real cart. The pointer touches one control, the checkbox, and never touches Place order, a payment row, a billing field or a quantity. After a pause the page is cut back to its opening state and the loop restarts; that cut is instant, never an animation, because rolling $162.00 back to $90.00 would stage an order shedding units it had already accepted, which nothing published describes.
LUMÉ is a demo store; the prices are its catalogue’s.
▲ +73% uptake** Printed because our own landing card prints it. The origin is 8theme’s marketing page, in the section they there tag Double Order Upsell — “Bonus packs and bundles can boost sales by up to 73%” — credited to PickyStory, a bundling vendor, and the bare name is the whole citation; PickyStory’s own publication could not be located from here. Three gaps no wording closes: their subject is bonus packs and bundles, not doubling an order; their sentence measures sales, while our card prints uptake, a take rate and a different quantity; and our card drops their “up to”. The documentation article carries no performance figure of any kind.

Checkout OffersWhere it shows
The article lists four, quotes them, and marks none of them the default. Its only steer is a tip.
Click a position — the card moves in the preview.
Placing it by hand
Every claim above about this booster is quoted from one article, dated 20 January 2025, and from the seven screenshots on it — the two exceptions name their own sources on the spot: the benchmark chip in the hero, and the by-hand note directly above. What this page does not try to be is an implementation reference:
Drawn, not captured — LUMÉ demo store.
Templates & appearance
Minimal is the bare box their own Template preview draws; Colorful is the strip-and-badge card their frontend screenshot draws.
Three fields, three strings, taken character for character from 8theme’s own screenshots. Both screenshots clip the button field at “…<strong>{discount} discoun”, so the tail above is read off the rendered frontend, not off the field. Under Minimal the strip and the badge are not drawn at all — that is how their own Minimal preview draws the block, and the Appearance panel beside it in that screenshot has no Section subtitle field either. A fourth field, Section Title, is named in the prose and appears in no screenshot — it is not drawn here. Styling is not represented at all: the screenshot printed under it belongs to another booster’s article.
The math
Nobody is converted here — the booster charges for a second copy of what is already on the order. Say 400 orders, 8 in 100 tick, a $60 order doubled with 10% off the doubled order: 400 × 8% × ($120 − 10% − $60) = +$1,536/mo.
The control room
Six panels, top to bottom: Template, Appearance, Discount, Display Settings, Conditions, Optional Settings. Where a value appears below, it is the one visible in that panel’s screenshot.
Tap the chips — the rule sentence rewrites itself. Every option here is one 8theme publish.
Minimal — “A clean and simple design that focuses on functionality and clarity.” Colorful — “A vibrant and visually engaging design with bold colors and highlights.” Their Template screenshot opens on Minimal, and the preview pane beside it draws the block as a bare dashed box. They add that the choice may affect the availability of some display options in Appearance — and their two Appearance screenshots do differ: one shows Section subtitle, Highlight badge and CTA Button Text; the other, the one taken with Minimal selected, shows only the last two.
The strings in their screenshots, character for character: Section subtitle Up to {discount} · Highlight badge Best offer · CTA Button Text Click here to double your order and get a <strong>{discount} discoun — clipped there in both screenshots. The rendered result reads Click here to double your order and get a 10% discount!, so the closing fragment used on this page is read off the frontend, not off the field. All three carry the hint Available placeholders: {discount}, and the prose adds that {discount} inserts the configured value — which resolves with its unit, since their two renderings print 10% discount and $15 discount.
Section Title: “Defines the main heading displayed above the booster block.” Prose only. Neither Appearance screenshot has it, and the second begins at the panel header, so it is not a crop. This page draws no title and does not claim the field exists. The prose also calls the button field Custom Button Text, where both screenshots label it CTA Button Text.
Their four: layout spacing (padding and margins); container styling (border radius, border colour, background); typography for titles, subtitles and badges; CTA button colours and fonts. Plus their hedge: “Some style options may vary slightly depending on the selected template.” No value from that panel is quoted on this page: the screenshot printed under it is the Smart Product Recommendations article’s own image, filename and all, and the prose beneath it still says “the recommendation block”.
Discount type, a select with two options: Percentage discount (%), checked in their screenshot, and Fixed cart discount ($). Discount value ($ or %) — 10 in the screenshot. Coupon display name — Discount. The last two appear in the screenshot only; the prose never mentions either, and never says what the coupon name prints, or where.
Four checkout positions, quoted in full further up this page, no default marked, no screenshot of the panel. Conditions is optional in their own words — “Add conditions if you would like to personalize based on the items in the cart, order total etc. (optional)” — and offers seventeen in four groups: eight on the Order (products, categories, tags, SKUs, number of line items, item quantity, applied coupons, order total), four on Purchase History (first order, orders made, orders made with specific products, total spent), three on the User (user role, user logged in, specific users), two on Date & Time (time, days). Their screenshot has the list open, which is why no operator and no combining rule is visible.
Priority 10 · Start date · Set end date (a checkbox) · End date. The pickers are day-granular with no time of day, so hour-of-day targeting comes from the Time condition instead. What Priority orders, and what happens when two boosters both qualify, the article never says — the field is in the screenshot and nowhere in the prose.
The booster duplicates the whole cart, so it has nothing to pick, and no products or categories field is shown or named anywhere. Their FAQ does point at Conditions when asked about per-product discounts, but Conditions gate whether the booster shows, and that answer slides from “discount rules” to “when the offer appears” — so this page does not claim per-product discount rules.
Any multiple other than two; whether unticking puts the cart back; what happens when stock is short of double; whether a copy is a second line or a larger quantity; how the discount meets tax, shipping, coupons or another booster; whether a fixed cart amount can exceed what the copies are worth; product types beyond simple and variable. Unpublished, all of it.
The article says nothing about analytics — no take rate, no reporting, no A/B split. And it carries no performance figure of any kind.
Make sure the booster is assigned to valid product types (simple or variable products); ensure the selected display location (e.g., checkout positions) is supported by your current theme; check that the booster is not limited by scheduling settings (start/end date) or restricted to specific user roles; try temporarily disabling other plugins to rule out potential conflicts (especially pricing, discount, or checkout-related plugins). And one more: price a doubled order against your stock and your margin before a sale — the copies are real goods leaving the shelf.
FAQ
It puts one control on the checkout page. In 8theme’s words the booster “offers customers a quick and tempting option to double the quantity of the product they’re about to purchase — often at a reduced price”, and it is “designed to increase average order value by encouraging volume purchases with minimal decision friction”. What the press does is stated plainly: “all items in the cart are duplicated”, and “the cart total is instantly updated, and customers can clearly see the additional products and applied savings before completing the order”. One tension inside that account is worth naming rather than smoothing over: the opening sentence says the product, singular, while the Frontend Result and two separate FAQ answers say all items in the cart. This page follows the three that agree with each other and duplicates the whole cart.
Their FAQ answers yes, and then moves: “You can configure different discount rules for specific products or categories using the Conditions section in the booster settings. This allows you to apply a discount only when certain products are present in the cart — giving you full control over how and when the duplication offer appears.” That sentence opens on different discount rules per product and lands on when the offer appears, and those are two different things. The Discount panel holds one Discount type and one Discount value for the booster, and shows no product or category field at all; Conditions is introduced in their own words as “Add conditions if you would like to personalize based on the items in the cart, order total etc. (optional)” — a gate on whether the booster shows. So what is documented is one rate, shown or withheld by condition. Genuinely different rates running side by side in one cart appear in no screenshot and in no sentence of the prose — and since the booster duplicates the whole cart rather than a chosen product, there is nothing inside it to point a second rate at. Worth an answer from support before you count on it.
Everything. Their FAQ is direct about it: “When the customer clicks the “Double the Order” button, the booster duplicates all current items in the cart. This is not limited to a single product.” On product types: “It supports both simple and variable products. For variable products, the selected variation is duplicated along with the quantity.” That last sentence is why the demo at the top of this page carries a variable product with a chosen size and a quantity of two. Whether a copy arrives as a second line or as a larger quantity on the line it copies, the article does not say; the demo at the top of this page draws the larger quantity, and that choice is its own.
Display Settings asks you to “choose where on the checkout page the Double the Order booster will appear” and lists four positions: Before Payment Gateways, Before Place Order button, After Place Order button, and Bottom of the Checkout Page. No default is published, and Display Settings is the one panel on that page with no screenshot. Their only steer is a tip — “Placing the booster right before the “Place Order” button can be especially effective, as it catches the shopper’s attention at the last decision point” — and that is also where their own frontend screenshot draws the card, below the payment section and directly above the button. There is no manual route to weigh against it: asked about Elementor and custom templates they answer that “the booster works automatically using WooCommerce hooks. There is no shortcode. You don’t need to place it manually — it appears in predefined checkout locations.” One stray clause runs the other way: the Appearance section opens by describing how the booster looks “on your product page”. Every other statement on the page places it on the checkout.
The prose calls it a button seven times, and names the field Custom Button Text where both screenshots label it CTA Button Text — but both rendered images, the frontend one and the preview inside the Template screenshot, draw an unticked checkbox inside a dashed box. This page draws the checkbox and keeps the screenshots’ field name. Whether it arrives ticked, nothing anywhere says: 8theme draw the box unticked, and that is the whole of the evidence. Nor is there any account of what unticking does, or of putting a doubled cart back. If that matters where you sell — a pre-ticked add-on is a negative-option sale and is restricted in several markets — it is worth a run on a staging copy before a sale.
The Discount panel holds three fields: Discount type, a select whose two options are Percentage discount (%) — checked in their screenshot — and Fixed cart discount ($); Discount value ($ or %), showing 10; and Coupon display name, showing “Discount”. The prose never mentions the last two, and never says what the coupon name prints, or where. What the fixed option actually does is the one thing the article contradicts itself on: the prose says “Fixed Discount – applies a specific discount amount (e.g., $5 off) to each product in the booster”, while the select in the screenshot calls it a cart discount. Nothing in the article resolves it, so neither does this page. {discount} is the one placeholder, and it resolves with its unit. Tax, shipping, existing coupons, sale prices, stock and any multiple other than two are unpublished.
