First thoughts ... ( never mind those )
Second thoughts ... you're using a lot of tables...
I ended up creating a div class to replace most of the box class before and this GREATLY enhanced the site in my mind ...
Not great for SEO .. there are two major modules for SEO with OSCommerce you should check them out
there is too much white space up the top left ...
The two flags ... are pretty poor quality ...
While OS Commerce calls them Manufacturers ... I'd really replace that wording ..
The page is a bit ... static ... nothing really happening / moving ... while I don't like flash websites .. I think a bit can greatly enhance a static page.
Again there is a Specials module that will do this with nice transitions from page to page ..
The buttons could be replaced by some nice aqua style buttons ... the default ones are quite hidious TBH
Not too keen on the fixed width either ...
Last thought .. girl on top right looks more slutty .. than
sexy ... but thats probably a personal preference thing
Apart from that quite nice
