A practical example
Example: a sports retailer runs a seasonal sale alongside a coupon code.
The engine must decide whether the coupon applies to already-discounted items, whether free shipping survives when the discount drops the cart below the threshold, and which discount the customer sees first.
What to evaluate before investing
- Ask how stacking rules are configured: can you mark promotions as exclusive, stackable, or combinable in a defined order, without custom code?
- Check whether the engine evaluates rules in a predictable, testable order, and whether you can preview the applied price for a sample cart before launch.
- Verify coupon controls: usage limits per customer, expiry handling, and whether codes can be restricted to products, tiers, or channels.
Limitations and tradeoffs
Flexible stacking rules are powerful but error-prone; a single misconfigured combination can apply unintended discounts across the whole catalog.
