shop pay discount stacking with promo codes
The actual problem
Shop Pay or wallet promos stack with store codes and erase margin on paid orders.
Do this
- Place test orders: promo code alone, Shop Pay alone, both together.
- Disable combine rules on high-value % codes.
- Document which wallets are allowed with which campaigns.
- Scan for other stacking paths with Tillkiln before the next promo blast.
