Adding orders are mainly divided into the following three situations:
1) The original order has already used the full discount coupon, and additional order can no longer use the coupon
2) The original order has already used the discount coupon, and the additional order can enjoy the same discount
3) The original order does not meet the conditions of using the coupon, and the conditions is met after the additional order then the coupon can be used for deduction.
