I would imagine that it depends from the company who you buy the hosting from...I have HG business package which costs me $14.99 a month and it offers UNLIMITED domains to be hosted on.
Well I have been with HG for the last 4 years, 3 of them with a dedicated server and the last year with a shared hosting account and I havent any problems with them, I would definately recommend them in every way, but thats me![]()
