Independent alignment of a single secondary menu item

Hi.

I have set up a site using the secondary menu in the header. I have relocated it from the default position to below the primary nav area and everything is working great. But now the client has asked to add an additional menu option – but to position it in a different area than the other menu links.

you can see it here: http://shred360.com

What I need to do is isolate the last menu link in the secondary menu titled ‘Enter Promo Code’ and float it out to the right side below the telephone number in the red box.

I have tried several approaches but nothing has worked.

Any suggestions?

thanks
