If you're willing to do a little more work, you can do it yourself. Get a cheap hosting site for around $5 a month, and use one of the many free open source ecommerce platforms. I've done that with OpenCart, and it's very nice. Most of the hosters offer a one-click install of the stores. HostGator has a plan for just $2.75 a month (pay for a year) with a free domain for a year. There are lots of others to choose from. The more you pay, the easier it gets. Check out Squarespace, stores start at just $18 a month, and it's pretty easy (and pretty).
