Promotions
Offers that apply automatically when the conditions are met, with no code to enter.

Common patterns
- Free shipping over NT$1,500
- NT$300 off orders over NT$3,000
- 40% off the second item
- 15% off everything in a given category
Once configured, the cart on the public site shows "applied" by itself and the customer does nothing.
Question: Which one wins when promotions conflict?
Whichever priority you set. Among promotions at the same priority, the system picks the one most favorable to the customer.
