The logo 'feels' weird. The 'Online Shop' is larger than the 'Keimos' logo itself and for me that just doesn't flow logically.
I like drop down menus, I don't like the rollover effect on the buttons themselves, but that's just my personal preference. Also, the drop down menus are actually 'transparent' you can see what I mean by putting your cursor on 'IT Courses'

I went through a checkout process so when you see order# 08108-1558
Total:£250.00GBP
its not real.
The shopping cart has ONE too many steps and then it dumps you into paypal.
I don't mind paypal as an option, I don't like it as the ONLY option....
I recommend getting a toll free (free phone I think you call it) and getting it in the logo so that it is visible in every page.
