Well, not me, obviously! But take a look at Chicken Pots. This new site is just for online sales of, well, chicken pots! The limit of five products on the free webs.com sites makes them just right for focusing on one design of pottery. I must say I'm particularly pleased with how the site has turned out.
I've only really got plenty of stock in this one design, but have ideas for more mini-sites in due course.
