Tiered programs add another decision: whether rewards stack, replace one another, or depend on different cart measures. For where to place a discount field in the cart, the useful decision is specific: place the field near pricing while keeping the subtotal and checkout relationship clear.
Practical method

Start with the shopper-facing rule, then work backward into configuration and QA. A dominant empty field can send shoppers away to search for coupons Treat that warning as a launch condition, not a footnote.

For where to place a discount field in the cart, record the current shopper state and the result this decision should produce.

Pre-launch review
What to check before the change goes live
Use realistic products and storefront entry points. Test the normal path, then reverse the action and force an unavailable or invalid state. The cart should preserve accurate totals and a reachable checkout action throughout.

Measurement
How to review the result
Review reward exposure, progression, qualification, redemption, margin, and completion. Separate shoppers who naturally build larger baskets from behavior caused by the reward experience.
Write down the audience, date range, event definition, and operational costs before comparing outcomes. If the change affects several things at once, the result may describe the combined experience but cannot isolate which detail caused it.
