Ed,
Questions and comments.
Question:
Did you realize that in Firefox, that nice liquid blue logo doesn't.... wait... now its there!? Weird - was just slow I guess.
How did you create the paypal cart at the jewellery site? Isn't the go-cart module only "buy one item at a time" or did you write more code?
Comments:
Nice clean and functional sites.
BUT I'm not sure if I looked at it some time ago, but when I tried out the "add to cart", there was already an item in the cart. I think I might have looked at it, a month ago when you first posted the site.
You might want to think about putting an "expiry date" on the pay-pal cookie, if that's possible.
