The design is very complex. I would defenitely start with sorting your design to less links and text. Try to focus on your customer. The "special offer" is an advertation right? Try to keep this as small as possible.
I think the header is too high, try to focus your most important information on the topleft of your design (as this is the first what visitors will see)
Good luck! :)

Yes special offer is an advertation. Thanks
