It loads pretty fast for me however there are a few things you could probably do to reduce the size of the page. For example under the best sellers on the front page, each of those thumbnail images is around 40KB each. When I look at the image directly I can see that it is much bigger than the actual thumbnail size. If you generated more appropriate sized images for those, you could probably save around 100KB.
Unrelated to your question though when viewing your site at the top, your address text is on top of the text about how to size up for updates and discounts. I'm using Firefox 16.
