Haven't had time to really look over all of it yet, but what I've seen looks nice. I'll try to be more thorough later. A few things that stick out at the moment are:
The green font color is hard to see against the blue background of All Categories
Trying to access the Terms and conditions link from the sign-up page yields this: The requested URL /static_pages/terms.htm was not found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
On the same page Australia is listed after Zimbabwe in the drop down menu
On the same page in the left-hand columns, "City, State(or Region)" needs a space between state and the parenthesis. It would look better as "City, State (or Region)" Also, "Terms And Conditions" might look better without the "And" capatalized. "Terms and Conditions". Pretty much a judgement call there.On the legal page "guarantee" is misspelled. you have it as "gaurantee"
