Has anyone used Shopify.com?

I am looking for some feedback from anyone who has used shopify.com as an ecommerce solution. Specifically, are there any quirks to this system?

How flexible is the design interface?

 

I used Shopify before they began to charge (when they were a free service) but that was ages ago. I decided that I wanted to have something more flexible than what they were offering..

Currently I am using Creloaded for my stores.

Hope this helps

 

Seems pretty straightforward, but I went with Corecommerce.

 

The only thing about shopify is there templetes, the downfall is that take a percentage out of your total revenue each month =(
