The text boxes didn't respond when clicked (but could still fill it on, no cursor and the hint text didn't hide on click).
The buttons and general UI and clunky and outdated. When I clicked into a wishlist then clicked to add an item nothing happened. IF I double clicked the prompt would animate in and then disappear instantly.

Switching to Firefox fixed a lot of these issues but made new ones (why can't I set my currency in account? Why do I have to see $ currency and then manually change it- just let me put it in myself if you don't know!)

OVerall a very frustrating 10 minutes spent trying to use this site.
