Product Add-Ons
Optional products from your own catalogue, each discounted on its own, listed right at the Add to cart button.
Built for WordPress · WooCommerce
LUMÉ is a demo store — its numbers are illustrative.
▲ up to +20% AOV** 8theme’s own SalesMax page states “Increase AOV by up to 20% with product add-ons” and attributes the figure to WooCommerce. It is a vendor-cited benchmark for add-ons in general — not a SalesMax measurement, not a promise. What you actually get depends on your catalogue, your price points and which extras you choose to offer.
Scene 3 of 6 in the shopper journey: the product page. This booster runs here. In its demo two extras are ticked above Add to cart and the order goes from $79 to $106.

The display settings for this booster are deliberately short: the block goes before the Add to Cart button or after it.

Templates
Minimal or Colorful, and three fields in your own words. The discount you pick lands on each add-on separately.
The math
Say 400 orders a month, one in five picks up an extra, and the average extra is worth $24 after your discount: 20% × $24 × 400 = +$1,920/mo. Press the keys.
Targeting & setup
Filters decide which product pages carry the block, and whether a product must match one of them or all. A start date and an optional end date do the rest.
Tap the chips — the rule sentence rewrites itself.
Then pick the booster type called Product Combo Deals, name it, configure and save. That is the type 8theme’s own “Product Add-Ons” feature links its documentation to — same booster, two names, and it’s worth knowing which one to look for in the picker.
Display the booster on all product pages across your store — the widest setting there is.
Limit visibility to products belonging to selected categories: cover Outerwear once and forget about it.
Show the booster for products with matching tags — cross-category slices without touching your category tree.
Target specific SKUs for precise control, which is the filter to reach for when the products you mean share neither a category nor a tag.
Select individual products manually when the list is short enough to name.
The booster is triggered if the product matches at least one of the selected conditions — broad reach.
The booster appears only if the product matches every selected condition — highly specific targeting.
Use WooCommerce’s own related products — it decides the relation from shared tags and categories — or the Cross-sells and Upsells you already picked under Linked Products on the product itself.
Or skip the relations entirely: search for products and add them, and that set is what the booster offers.
Lock the quantity to a number you set, let the customer change it in the cart, or sync it with the main product — add two jackets and two of the extra follow.
Add-ons arrive as ordinary cart lines, each carrying a badge — the documentation’s example is literally Add-on — so nobody has to guess which lines came from the offer.
No discount, a percentage, a fixed amount, or Free — and each one applies to each add-on individually. A $3 fixed discount on three add-ons is $9 off, not $3. Free items show in the cart at $0.00.
One store-wide setting decides which price the discount is figured from, and products that are already on sale can be left out of it.
Set the day the booster activates — for a launch or a seasonal push — and tick an end date to have it switch itself off. Dates, not hours.
The vendor’s checklist is three lines long: make sure the filters match the current product, check that the selected products are published and in stock, and make sure the booster isn’t restricted by schedule or user role.
FAQ
Yes — you can create as many boosters as needed, each with its own targeting and logic.
Yes — variations are supported and customers can select attributes before adding to cart.
The display settings give two positions: before the Add to Cart button, or after it. The vendor’s own frontend screenshot shows the first one — the block sits directly above the quantity field and the button. If you build your product template in Elementor, you can insert this booster with the SalesMax widget instead.
To each add-on individually. Choose no discount, a percentage, a fixed amount or Free, and it applies to every product in the booster on its own — a $3 fixed discount takes $3 off each add-on, not $3 off the set, and Free items appear in the cart at $0.00. A store-wide setting decides whether the discount is calculated from the regular price or the sale price.
If they exist as WooCommerce products, yes: this booster offers published, in-stock products from your own catalogue and adds them as ordinary cart lines, so a gift-wrap product or an extended-warranty product behaves like any other add-on. What the documentation does not give this booster is a free-text option field — there is no engraving message, no monogram box, no file upload. If your extra needs the customer to type something, this isn’t the booster for it.
