Of course you can. There are two situations:

1. The merchant stipulates that there must be a certain minimum order quantity, that is, a minimum order quantity is stipulated. In this case, you cannot bid for only one piece. However, if you contact the seller and buy at the retail price, you can almost only bid for one, but the price will be much more expensive than the above. You can also directly buy at the sample price, or you can only bid for one.

2. The merchant stipulates that the minimum order quantity is one piece. In this case, you can directly bid for one piece without any additional conditions.
