I have just checked carphone warehouses site and the navigation bar on the left does not appear to be working.
Whatever link you select takes you to a error page. Which basically makes their site useless.

Has anyone else noticed this, or is it just me having problems with teir site. Makes me wonder how long this has been like this as i seem to send them a lot of traffic, and get poor results compared to similar merchants.

Anyway with their navigation not working their site is virtually useless.
