Does Watson's shopping promotion support returns?

Watson's shopping promotion only accepts full return, not partial return. If you need to exchange goods, you need to return the whole order first. In reverse transaction (such as return/refund), only the actual payment amount of the cardholder after enjoying the discount will be refunded, and the preferential qualification will not be compensated. Savings goods such as bills of lading and stored value cards do not participate in this activity. You can't participate in the preferential activities on the same day, and you can't make out an invoice for the discount.
