Make it work at 800x600 without any side-scrolling, since that’s the resolution most internet cafes run at (and lots of computers in Taiwanese homes - they don’t like squinting to read, I guess).
Lose the blue bevelled buttons, they’re old fashioned and don’t really serve any purpose. Simple text on a coloured background would look better and load faster. This especially applies to the “paint splash” buttons on the inside pages They’re too big, too bold, too distracting, and they serve no purpose.
Having the shopping section on the front page is definitely a good idea, though the breakdown seems kinda arbitrary. Perhaps reorder it so it seems more logical. Also, do something about “Bathandhouse” and “Lcdtv”.
Bring back the “Island wide shipping for up to 5kg only NT$80” from the old front page, it’s a great hook because it’s the first question people will have.
Finally, consider hiring a professional designer to make some templates for you (which you can then insert content into yourself when you need to). I can recommend someone who can probably do it for a few grand, if you like - PM me.
