(2) Send the 20 yuan coupon to the e-mail address of the shopping account 30 days after the successful delivery of the order (please ensure that the e-mail address of the shopping account is available correctly).
(3) The amount of a single order is not returned cumulatively, that is, an order can only be returned once! If multiple orders under one account meet the above conditions, you will get coupons respectively!
(4)20 yuan vouchers can only be used for re-purchasing books (except imported books): when re-purchasing books and settling in the settlement center, you can enter the book voucher code up to 20 yuan.
Probably, the vouchers in 20 yuan can only be used to buy books next time, and will be sent to your mailbox for registration in the form of email, which should be a password or something. My book has been here for more than 20 days, but I haven't seen the coupon ... hey.
