Does anyone here ever get those in the mail? I get them and I had a bank call me once to tell me that someone had forged my signature to deposit one in an account he created. They caught it thankfully. I'm leary about them coming in the mail.
You can just call your credit card company and request them never to send them. They have a horrible interest rate anyways on top of cash advance fees, so I can't imagine why anyone would use them.
