If you want a free website that you can sell your items from I suggest using
Freewebs.com - it's easy to use and you can use their "wizard" to customize your site to the way you want it to look or use one of their free templates which are semi-customizable
Also, if you have paypal you can use the free "e-commerce" system where you can make shopping cart and buy it now buttons for items you sell that allow customers to pay for your items using Paypal accounts or credit cards
The problem with paypal (Im not sure if it is a problem anymore, actually) is the fact that yourwebsite will not show up in the search results - actually I think my latest website does so that may have changed...
What you can do if your website doesnt come up on a search engine is get a blogger.com site with google for your site as well - so that it will show up in the search results if you name it the same as your store name...
you can also add your freewebsite to all kinds of webrings and links pages
getting a myspace for your business that links to your catalog is always a bonus
