If I go to www.cox.net, I get redirected to: »ww2.cox.com/myconnection/home.co ··· home.cox
The shop link there is the same one I gave earlier.
Well, after I cleared all my Cox cookies, and go to www.cox.net I get the Cox intercept page where it asks your location. After that going to cox.net redirects me and gives me the oklahoma city shop link if I click on the Shop tab. Probably have different looking pages based on your area or something.
If I actually try to login with the link you give, I get an "Ooops, we can't find that page" afterwards.
