I hope I put this in the correct section...
Haven't been on Dillon for a while, found out today that they updated their log-in system back in June. They now use email address for logging in instead of the old username. If you haven't been on their site in a while you'll have to create a new account. I called them with another issue this morning, and while I was on the phone they transferred all my previous account info over to the new one.
Just and FYI if you are a member of their website.
