Horrendous "support" for non-IE browsers!
We were experiencing the same problem with not being able to access the website for weeks and finally thought of digging out their customer service number from cached webpages - it is 1-888-673-5426.
After talking to one of their customer service representatives, it appears that they only support Internet Explorer or Netscape - if you are using a browser like Firefox or Safari (who does not use Firefox?), the website will not even load and it would appear to the end-user that the server is down. Which webmaster does not have the skills or common sense to return a simple page to the user and message saying "Please use IE 5.5 or higher"? Also they have all our email ids via which they send us promos, could they not send out a broadcast about this website limitation - it has worked in the past with firefox. In any case, we asked the agent to notify these basic issues to their web support team.
In this day and age, they MUST support Firefox since most US and Europe customers use such alternative browsers.
