Nicely done, Michel... but then I love Wordpress. I'm a huge fan of WP.
I really like how you organized the categories, as well as offer archives. It is nice to see a WP installation so well organized.
My only concern echoes those above -- it is very cluttered, and I don't know where to start. It feels overwhelming. Since the Google Ads look just as important as the menu and the text, I don't know what is
really important. It takes some work on my part to find the "real" content, figure out where I should click to see the meat & potatoes.
Honestly, unless the primary goal of this site is to sell ad-clicks, I would drop the AdWords on the right, and stick with horizontal AdWords "bars" at the top/bottom. Yes, I realize that the Adwords column on the right is some seriously prime real estate

but if your site exists to sell something
other than AdWords, then the AdWords are seriously detracting from the main product.
I think adjusting where your AdWords are shown, and how they are displayed, will go a long way to create more white-space and let the viewer's eye "rest" -- we won't have to work so hard at reading it, which will make it more of a pleasure to spend time at.
Just my thoughts, hope it helps somehow.
