INVESTIGATION LOG: #8821 Target: Nike.com Analyst: @SarahK

Does the Nike Student Discount stack with Sale Items?

VERDICT: FALSE

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:
  1. Checkout Cart 1 with only Full Price items (Apply Student Code).
  2. 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.
