What happened when I received a text message from Vipshop, but there was no coupon in my account?

Hello, dear members. If the coupon hasn't arrived yet, I suggest you log in to the Vipshop account and click "My Coupon" to activate the coupon. If the coupon has arrived, put the goods in the shopping bag and click "Use coupon" to follow the instructions. We look forward to your continued support for Vipshop. thank you
