I am looking to pay under $15 a month for the following:

At least 50 mb webspace
About 5 gigs of bandwidth
Web Shopping Cart
NO ADVERTISEMENTS
Reliable
E-mail accounts like anyuser@myname.com

I have an internet store to sell my products on. I would like to know if this would be enough space.

What sites can offer things

umm normally I suggest www.hostingchamp.com and www.buznet.net. Those 2 fall under this category. Unfortunitely I dont think either of them have a shopping cart. But plan wise they give you everything you need under 15.
