Stop rebuilding test carts by hand before every sale. CommerceLatch checks your existing native Shopify discounts, then compares the expected discount with the result in a fresh cart. Test amount-off, Buy X Get Y, free shipping, and eligible discount combinations. Simulate scheduled offers before they go live. See what needs attention and save the result. Work inside Shopify with no extra account or API key. No orders, payments, or changes to your promotions.

• Prove amount-off, Buy X Get Y, and free-shipping outcomes
• Simulate scheduled promotions before they become active
• Verify mutually combinable discounts in one Storefront cart
• Catch empty targets, unreachable minimums, limits, and conflicts
• Open privacy-safe receipts with Expected and Actual results
