Has anybody used free webstores or low subscription webstores

I am thinking of setting up my own webstore preferably one i can get my own domain name
I have seen sites such as groovycart also as an auctiva user i know they offer a subscription service (auctiva commerce)
But are any of these any use does anyone use them and make sales or should i forget these and pay for a custom built site

I've used Zencart to extremely good effect in the past. Free cart, skins to customise it are around 150US, but I'm yet to find a skin that is the perfect fit, they will usually require some adjustment.

Now Zen has a very good back end for admin, however if you are accepting money or storing customer's details on the site, then I would suggest getting some security checks in place as I am not sure about just how secure it, or any free site would be.

Having your own site developed will be the most expensive option, but you will get what exactly you want, and that's a massive bonus if you can afford it.
