Beijing Coupon: Universal in JD.COM, with no restrictions on use, category, store or geographical location. Multiple Beijing coupons can be used for a single order, and the payment can be reduced or exempted according to the total face value, and cannot be superimposed with the eastern coupons. You can't use special goods. When submitting an order with Beijing coupons, if the amount of Beijing coupons is greater than the amount of goods to be paid in the order, the difference will not be refunded.

However, the electronic vouchers exchanged for credit card points of CCB can only be purchased from JD.COM. COM's self-operated goods. The specific scope of use and rules shall be subject to the electronic card of JD.COM in JD.COM Mall. This coupon is for one-time use only, and the remaining amount will not be changed without issuing a new coupon.
