I actually really like your site. It is very basic, but that is a good thing. I love the color scheme and the navigation is thought out very well. The only thing I could see changing is maybe adjusting the look of the price tags. They look out of place on the page. If you could maybe use a different font and maybe a small window with a drop shadow behind it.. it really think it would make the prices look more appropriate for the great site. I would also suggest posting competitors pricing in black next to your prices in red. It makes people feel like they are getting a great deal.
From my side it is a awesome site and no need to anything rather then adding new and attractive contents
best of luck
