I'd appreciate if you all could review our site: http://www.spynyc.com . I'd appreciate any design critiques in general but my real concern is about the one page checkout. About 3-4% of our visitors add something to the cart. Of that about 40% proceed to the one page checkout. But of those that proceed to the one page checkout about 30-35% actually complete the checkout. This is completely baffling to me and I cannot for the life of me figure out why people are adding items to the cart, clicking proceed to checkout and then abandoning the checkout page! Personally when I click checkout, I usually want to buy the product so I know something must be horribly wrong with our checkout page but for the life of me I cannot figure out what it is.

Any advice or criticism would be GREATLY appreciated. This issue has been driving me nuts!
