Validate a discount setup

Oxify doesn't have a tool that simulates a cart and reports what would happen at checkout. To confirm your reward configuration before launch, check it in these four places instead.

What to check

• The preview — The Cart Editor preview shows how the progress bar, gift cards and labels will look, for the market selected in the Market dropdown. It doesn't calculate checkout discounts.
• A real cart — On your storefront, build a cart that crosses each threshold. Confirm which tiers unlock, which products are added as gifts, and the savings you see at checkout.
• The discount in Shopify — In Shopify admin, open Discounts and confirm Oxify Cart Unified Discount is listed and active. Stores still on the older setup have IA Cart - Free Gift Discount, IA Cart - Order Discount and IA Cart - Shipping Discount instead.
• Conflicts — Add a discount code to the test cart and see whether it combines. See Stacking rules with Shopify discounts.

When to use it

• Before a big sale — Confirm new tiers behave correctly under realistic carts, in each currency and market you sell in.
• After migrating to the unified function — Verify nothing broke.
• When a customer reports an issue — Rebuild their cart and see what happens.

Diagnostic page

For a technical read-out of your free-gift discount, open https://YOUR-STORE.myshopify.com/admin/apps/cart-drawer-upsell-free-gift/app/diagnose (it isn't in the menu). Free Gift Discount Diagnostic shows whether Rewards is on, whether the discount exists in Shopify and its status, and the settings the checkout discount can see, with a one-line verdict. Share it with support if you need help.
