Is anyone familiar with Yahoo Stores?

I know that they are pricey, but it seems that for someone starting out, they might be a good alternative for ease of having everything in one spot.

Has anyone had experience with them?

How do they compare to Amazon Webstore?

From what I've read, Yahoo Stores seems to have better customer service, and because it's been around longer, has alot of developers who can customize the site for you.

Any info would be appreciated.
