Very nice-looking site. I'd agree about the SSL certificate, and as expensive as some of your products are, I would expect a regular credit card merchant account instead of/in addition to Paypal.

Some of your images should be smaller (file size, not dimensions), like the two at the top of the Living Room product listing page.

I'm, seeing the dreaded IE red X image replacement in IE7 and IE8 at the right end of your header. The image name is logo_new_collection.jpg.

I might also remove the 'GB Pound' dropdown in the header, since that's the only currency you accept.

Overall, though, a great job.
