Ruixing can only use one group purchase coupon for a group purchase order. Each group coupon can only be used for one consumption, and multiple group coupons cannot be used at the same time. If you participate in group buying activities at Luckin Coffee and get multiple group buying coupons, you can use these coupons separately, and use one coupon for each consumption. Please note that the validity period of the group purchase coupon also needs to be noted, and the group purchase coupon must be used within the validity period.
