I perhaps am not expert enough to give advice, but the site is quick enough to load. I would have put the 'compare' advice on the home page, so people who visit your site, will get a little bit of understanding first. You could put it above the table of cards.
As for the table of credit cards, it appears on my screen slightly offset to the left. Is that how is it supposed to be? I would centralize it, but have no idea how to do it in dreamweaver as I have never used it.
Personally I would put a a light background colour, but that is just me and many others would disagree.
That's it mate, I hope it helps, but as I have said I am no expert, and I think that others will have many other suggestions. Take note because they are always helpful, they do know what they are talking about.
