There are lots of options here!
If you have a lot of products to sell, you could look to buy hosting only and use e-commerce software (such as CubeCart or OSCommerce)
Or if you only sell one or two items you could have a simple one-page website with "Buy It Now" buttons generated via PayPal so people can buy with a PayPal account OR with any debit/credit card
or
do you want hosting that will allow you to set up your shop online (Such as
http://www.uk2.net/e-commerce/ - �9.95/month)
Drop me a line if you need any more info!
