Will the US group send a message after the group purchase?

The group buying process is as follows: enter the group buying website, find the corresponding stores and goods, place an order, and pay after confirming the goods. After the payment is completed, the registered mobile phone will receive the corresponding group purchase code. Consumers can enjoy the group purchase price and discount with the verification code when they enter the store. If the consumer doesn't receive the text message, he can check it in the online order.
