seems to me it's a very simple way to sell ANYTHING online...

I have a friend/business associate that has used Yahoo Store for about 3 years. It is a very easy way to run an online store. This friend of mine has several brick and morter "western wear" stores, and he uses Yahoo for the online side of the business. You can check it out here, and if you feel like a cowboy you can get all the necessary accessories you'll ever need.

I purchase from several online stores that use Yahoo and they seem to run very efficiently. I've had contact with some of these "mom and pop" operations and they've only had good things to say about them.

I once had a client that I built a Yahoo store for.

I really did not like it that much at all.

You're very limited in what you can do with the layout, design etc.

Now on the other hand, I have also had some great clients that I have built some great shopping carts for :)

Ebay has some things like this as well.... and with their huge member base, is always a good place to sell things. Even if you do not sell much in reality, you can still get lots of exposure!
