50GB total is what you get if that is what is offered. They have no idea how many websites you're going to put on it but if they say you get 50GB of drive space then that is all you're allowed, whether you put one website on there or a dozen.
Ok thanks, just double checking since all the flipping guides say the 50gb is more than enough to host sites but it's not really.
That's the issue when people launch "flipping" guides and have never actually done it themselves
If you're just starting out, I would recommend being a hosting affiliate rather than reseller. If you start getting a lot of demand and can deal with the support required to run a host, then by all means off that as well, but starting out it's really not necessary.
