Add "Complete your routine" cross-sells to the cart. Suggest low-priced complementary items, single-tap add.
Want more control? See the expanded prompt ›
In the cart drawer, add a 'Complete your routine' cross-sell row. For each item in the cart, suggest a low-priced complementary product (under $20). Show 'Add for $X' button — single tap adds it.
- Price-capped suggestions (under $20) feel like add-ons, not new purchases.
- One-tap add with prominent price.
- Up to 2 suggestions, matched to the items in the cart.
- Hidden when no pairings under the price cap exist.
What you're trying to do
An upsell offers a better or bigger version of what's in the cart; a cross-sell adds a complementary product, like the brush, travel size or refill a shopper didn't think to add. Cross-sells raise order value with small extra items, and the low price makes them an easy yes.
Things to watch out for
- Price cap: under $20 by default; you can set a different cap per cart subtotal.
- Relevance: picked from products your customers buy together.
- Quantity: 2 suggestions at most per cart open; more feels noisy.
- Already in cart: Fudge leaves out items the shopper already has.
How Fudge does it
Fudge duplicates your live theme into a draft, edits the relevant template (product page or cart) with the changes your prompt requires, and tests against your real product data. Everything starts in draft — preview on any product or in the cart, tweak any detail, and publish when you're ready. Your live store stays untouched.
How cart cross-sells work in Shopify
An upsell offers a better or bigger version of what’s in the cart; a cross-sell adds a complementary product. A “Complete your routine” cross-sell row in the cart drawer shows under-$20 complements to what’s already in the cart, which adds to the order without feeling pushy.
When this is worth building
Build cross-sells if your catalog has clear complement patterns (skincare → tools, dress → accessories, supplements → tea). Skip for standalone categories.
What makes one great
- Under $20 (configurable) — feels like an easy add.
- Co-purchase data driven — pulled from actual order patterns.
- 2 items max per cart open — more feels noisy.
- Items already in cart excluded — no duplicate suggestions.
Pair this with cart upsells and frequently bought together. Fudge builds all three with its merchandising tools; for the manual route, see how to add cross-sells in the Shopify cart.
