As others have said, the Thumbnails are way too big.  They are huge, and some big thumbnails and some smaller looks very awkward and displeasing to the viewer.  There should be uniformity in size and the thumbnails should be smaller, maybe half what they are.  

Also on the product pages, the products promos are far too big.  One has to do a lot of scrolling in this layout to see everything, and if I can't even see the promo picture of the item I am browsing without scrolling to see the whole thing, then scrolling more to see the price, the content, etc, etc, then I am going to lose interest and probably not buy that item.

I don't like the fact there is no frame around the product and decription below that separates it from the body of the page.

Please change the layout to something more usable and friendly and less ugly.

On the plus side, I do like the purchased icon.
