On the specific operation process of group buying

Small cities are generally difficult, group buying has just started, and many are making progress. Including cooperation with manufacturers, you can buy this group-bought product first. If the group purchase is successful, he will give you the number and password, and you can go to the business activity place to get the goods. If you don't succeed, you will get a refund, something like this. There are so many group buying websites that I don't know which one is good. Look at this website in www.cahou.com, which has collected many credible group buying websites. This website is the best I have ever seen.
