The cost of the discount is usually borne by the merchant.
The 50% off credit card food promotion is a promotional strategy aimed at attracting customers and promoting catering sales.
In this kind of event, merchants offer food discounts so that customers can enjoy delicious food at cheaper prices.
Specifically, when a customer uses an eligible credit card to make a purchase, the merchant will calculate the discounted amount based on the discount ratio stipulated in the activity (usually 50% off, that is, half of the original price).
Customers only need to pay the discounted amount, and merchants need to bear the discounted portion.
