Just today I got a credit card offer in the mail for the Chase CO Mastercard. I nearly shredded it without opening it because I've seen similar offers on a regular basis.

This one was a little better than the others: no annual fee for the first year plus 20,000 bonus miles after the first purchase.

The offer code is P4Z, but I'm not sure if it is targeted or not. The phone number to call is 1-888-780-7420
