The Investigation
We detected a spike in failed verifications for student codes on Nike.com. Users reported the code was "Invalid" despite being freshly issued by SheerID.
Our investigation reveals it is not broken; it is gated. The logic gate explicitly checks for the `markdown` tag on SKUs in the cart.
Test Log (50 Carts)
Cart A (Full Price)
SUCCESS (-20%)
Cart B (Clearance)
FAILED (ERR_05)
Cart C (Mixed)
FAILED (ERR_05)
The Workaround
The Nike checkout logic applies the constraint to the entire cart if a single sale item is present. To maximize savings, you must split your transaction.
Protocol:
- Checkout Cart 1 with only Full Price items (Apply Student Code).
- Checkout Cart 2 with Clearance items (No Code).
Don't remember these rules.
The SimplyCodes extension automatically detects "Mixed Carts" and warns you to split them.
