Select the group purchase products you want to buy. No matter which group buying website you want to buy, you must register first and log in before you can buy it. Be optimistic about the following group buying rules, and the words "make an appointment at least one day in advance" will be written below.

After selecting, click Buy. At this time, you need to choose the number of copies you want to buy. And then pay.

Because you will be asked to fill in your mobile phone number when you register, your group purchase coupon number or password will be sent to the mobile phone number you fill in after you pay successfully. Generally, you will receive a text message within one minute of successful payment. It doesn't matter if you delete this message by mistake. You can go to this website again, go to "My Orders" to see the goods you have purchased, and then select "Send to Mobile Phone".

Then you can call the merchant to make an appointment. It is usually enough to make an appointment one day in advance, but it is not too late to catch up early. It is not excluded that there are businesses that are particularly hot, and the number of group purchase coupons received every day is limited.

When you go to dinner, tell the waiter that you are a group buyer, and the waiter will ask you to verify the group purchase coupon number or password. After verification, it can be eaten normally.

If you still don't understand, ask again.
