Still believable.

I didn’t believe it before. Even though I was studying this, I always felt that there was no way such a cheap thing could be bought by so many people. Moreover, if I paid for it and it wouldn’t be shipped, I would have to return it. The money will not be refunded, I have a lot to think about. Now I work in an online group buying company and started to get involved with the whole process, only to realize that it is actually just ordinary shopping, nothing much.

If the website has a refund agreement, it is usually mentioned on the website. The group buying website itself has profits. Of course, this is done by the salesperson, so if the things are cheap, you must grab them quickly or you will regret it later. Yes, but some group buying websites will set the number of people to buy in the future in order to attract people to buy. This is not very reliable.
