Coupon + cashback conflict checker

1. One primary path — Cashback portal click OR merchant coupon field — pick one primary attribution path.
2. Portal FAQ — Does the portal say coupons void tracking for this merchant?
3. Extension count — Only one cashback/coupon helper enabled for this checkout tab.
4. Code source — Dated official/partner code — not an undated "WORKING" screenshot.
5. Region & plan — Code valid in your EU country and for the cart you actually have?
6. Invite ≠ coupon — Do not paste a referral URL into a coupon box (see referral-vs-coupon guide).
7. Screenshot rate — Capture expected cashback % before paying.
8. Keep proof — Order ID + confirmation until rebate clears or ticket window closes.

When unsure, portal-first without rival extensions beats a voided rebate. Pair with coupon-hygiene and cashback-browser-hygiene.
