is an example of how a commercial web site should look. Tasteful and restrained design, everything you want to know at the click of a mouse, and quality products, well displayed.
It's hard to fault, and it seems nitpicking to try, but you asked, so there are three points:-
2. On your links page, put a little paragraph to say that you cannot be held responsible for the content of external sites.
3. It's not a great idea to have contact email addresses as hyperlinks - you'll be swamped with spam. Put email addresses in plain text - preferably as a graphic, so they can't be harvested by spam-bots. Let your customers do the typing.
That purple border? I see exactly what you mean, and the harder you look the more difficult the decision becomes - have you tried losing it, what does it look like?
My only thought was that the content might tend to look a little lost without the restraint of the border - on balance I think I might keep it.
