Test Shopify Discount Combinations with a Basket Matrix

Example: a free-shipping promise is ambiguous

A campaign might correctly apply an item discount while a minimum-spend shipping offer no longer qualifies. Inspect which total the offer evaluates and align the campaign copy accordingly. Hiding the second message does not make the combined offer clearer.

Approve the end-to-end result

Test the campaign link, cart and checkout, including removal of an eligible item. Record the rule identifiers and expected results. Repeat the relevant baskets after changing an app or promotion setting so a later configuration edit does not silently alter an advertised offer.

Should I test removal of a coupon as well as adding it?

Yes. Removing an offer or qualifying item can expose stale totals and misleading labels. Include the return to a nonqualifying cart state in the matrix. Confirm that the final checkout amount and explanation remain consistent after several edits, not just the first application.
