Thanks for the input everybody, here's a short Beginners Portuguese 101, from top left to bottom right:
EDIT
Promoções = Promotions
Leilões = Auctions (Base = base price, Actual = Actual Bid price)
Novidades = What's New
Destaques = Sort of Selected Products, these can be promotions, best sellers, etc. soon to be replaced with Product of the Day
Notícias = News
/EDIT
Although it is currently on a production server, I'm aiming for a quick loading site without too many scripts (I usually surf the web using Mozilla with scripts off), and the site engine that these guys bought is full of little javascript scripts that can be replaced with php.
All I need to do now to finalize this skin is complete the footer of the page.
