I found this through another team and wanted to share... (thanks Sarah!)
There is a company called "Peek" who does free video reviews of websites, generally 5 minutes long. You submit your shop URL to the site and within a few hours some random shopper goes through the site and points out it's strengths and weaknesses as they perceive them. It's a great video tool to see how a complete stranger looks at your site, and it's absolutely free! And it's pretty cool to see how someone else navigates your shop as you watch.
Here's the results I got from them after a review of my WornElements shop:

All you do is type your shop URL and email address and they email you back with the results. The site is here: peek.usertesting.com/
