Wix Stores just got an upsell engine.

With Bumps: cart bumps, checkout bumps, product-page cross-sells, frequently-bought-together bundles, volume bundles, BOGO and mix & match bundles, progress thresholds, gamified scratch reveals, optional add-on fees, and thank-you upsells.

No. When a shopper accepts an offer, Bumps adds the product to their real Wix cart as a normal line item and applies the discount server-side, either as an automatic Wix discount rule or as a coupon the app mints and applies for them. There is no code to copy, no code box to find, and no bounce back to the product page. Bumps also verifies the item actually landed in the cart before it shows the shopper a success state.

No. Bumps installs from the Wix App Market as native Site Plugins and renders offers in the standard storefront slots. Nothing is pasted into theme code, and uninstalling leaves no theme code behind.

Not natively. Wix Stores does not include order bumps or post-purchase upsells out of the box. Bumps adds them as native Site Plugins across the product page, cart, checkout, and thank-you page, with no theme code.

Install Bumps from the Wix App Market, pick a conversion-first offer template (cart bump, volume bundle, BOGO, and more), and publish. The offers drop into the right storefront slots automatically, and you never touch theme code.

Yes. Bumps is built for Wix Stores with native Site Plugins. It is not a Shopify app.

No to both. Bumps renders as a Wix Site Plugin inside the checkout page rather than sitting in front of it, and an offer draws nothing at all until its own data has resolved, so it is never in the path between a shopper and the Pay button. And it is designed to fail silent: if anything is off, the offer simply does not appear. It never blocks checkout and never removes items from the cart.

Through Wix. Bumps uses Wix-managed plans, so a paid plan is billed to the same Wix account that runs your site. No separate checkout, no second card on file, no invoice from us. You upgrade, downgrade, or cancel from the app’s page in your Wix dashboard. For what the plans cost, see the pricing question above.

Yes. Loud conversion design is the default. Branded mode adopts your primary color on CTAs. A Minimal / match-your-store look is available as an opt-in, and it usually converts worse, which we say plainly.

Yes, in two ways. If you run an A/B test on an offer (Growth plan), Bumps checks it daily and, once one version is clearly ahead, gives it 100% of that offer's traffic and drops the others to zero. That auto-promote is on by default, and you can also promote a winner by hand at any time. Separately, when several proven offers are eligible for the same slot, a Thompson-sampling bandit keeps shifting traffic toward whichever converts best. A brand-new offer added next to an established one waits until you archive the established one, so an untested offer never takes traffic from one that is already working.

Nothing is destroyed straight away. Uninstalling stops every offer immediately, removes the Site Plugins from your storefront with no leftover theme code, and revokes API tokens at once. Your offers, settings, and performance history are kept for 90 days, so reinstalling within that window puts you back on the dashboard you left rather than a blank one. After 90 days they are permanently deleted. One thing outlasts the app briefly: the automatic Wix discounts behind bundles and spend-goal bars keep applying until they expire, within 30 days.
