You want to buy wholesale online, and have that place ship to individuals other than yourself after they paid you for it?
There are places that sell things online and you can send those things as a 'gift'. But after the first few people find out where you are buying things from, and that you are charging a premium for going through you, the perception may not be good.
I do not know of any place that will sell cheap, and ship to different individuals, without putting their return address on it. In way that defeats the purpose of selling wholesale.
