Why Does CS-Cart Apply a Promotion to Some Products but Not Others?

A cart promotion may apply only to selected items because product, category, customer group, quantity, date, or coupon conditions differ. The storefront banner can describe an offer more broadly than its actual configured rules.

What to check

Inspect promotion conditions and priority, product and category assignments, customer group, cart quantity, coupon use, date range, and competing promotions. Reproduce with a controlled cart and compare the discount breakdown.

Recommended next step

Align the promotion wording with the configured eligibility or correct the rules after confirming business intent. Test qualifying and nonqualifying carts, including combinations with other discounts, before announcing the fix.
