Why does it feel like it's more expensive than the supermarket when you buy from store #1?

It's true that it's not cheap if you buy it directly. But now he has coupons. If you log in with your Alipay Gold account (not your original account), you will be issued a 100-15 coupon for the first time; and then you will be issued 2 100-10 coupons for 1 month when you log in for the first time each month. However, this coupon can not buy mother and child, clothing and many other categories of things, but only to buy rice, oil, food, drinks and other daily necessities (e-coupon on the detailed instructions)
