Key takeaways
  • Price-capped suggestions (under $20) feel like add-ons, not new purchases.
  • One-tap add with prominent price.
  • Each cart item gets its own complementary suggestion.
  • Hidden when no pairings under the price cap exist.

What you're trying to do

Cross-sells differ from upsells: cross-sells are the small add-on you didn't realize you wanted (a brush, a travel size, a refill). They lift AOV by adding small items, not by swapping for bigger ones — and shoppers love them because the math feels trivial.

Things to watch out for

  • Price cap — Fudge handles this: defaults to under $20; configurable per cart subtotal.
  • Relevance — Fudge pulled from co-purchase data, not random.
  • Quantity — Fudge calibrates to 2 max per cart open. More feels noisy.
  • Already in cart — Fudge handles this: those items are excluded.

How Fudge does it

Fudge duplicates your live theme into a draft, edits the relevant template (product, cart, or checkout) 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.

When cross-sells differ from upsells

Cross-sells (complementary lower-priced items) pair differently than upsells (higher-priced alternatives). A “Complete your routine” cross-sell row in the cart, surfacing under-$20 complements to what’s already in cart, lifts AOV 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.

Common questions

Can I pin specific cross-sells?
Yes — tag products with `cross-sell-for-<handle>` to force a pairing.
Does the price cap respect the cart's currency?
Yes — Fudge converts to the customer's local currency for display.
Can the cross-sell appear in the cart page (not just drawer)?
Yes — Fudge can mirror it to the cart page if you have one.
