I fell for the Traveler's Advantage $1 for $40 back on Ticketmaster tickets! Boy do I feel ***. It's a scam.
They know how to work you and will reassure you left and right that you're getting $40 today on the tickets that you just purchased through ticketmaster. Don't buy it. You'll try to get your money, they'll apologize and say how sorry they are that you were misinformed by Ticketmaster -- there's no cash back!
I actually cancelled my credit card after I read about all of the unauthorized charges by Traveler's Advantage. They just want your info so they can steal from you. Don't fall for it, please.
