The membership card can only enjoy the membership price when shopping in this supermarket, and you can also enjoy the discount of points!

Unless it is a shopping card, you can't swipe your card like a credit card. Shopping cards need to be bought with money, and there are certain discounts, such as 200 to 220 shopping cards.

But as you said, it was free at that time, so there should be no such problem. Don't worry!
