Here's the deal,...
When you get those pre-approved letters in the mail for everything from credit cards to 2nd Mortgages and junk like that, you know most of them come with postage paid return envelopes, right? Well, why not get rid of some of your other junk mail and put it in these cool little envelopes!
If you didn't get anything else that day, then just send them their application back! Just make sure your name isn't on anything you send them. Hell, you can send it back empty if you want. Keep 'em guessing!
Let's turn this into a chain letter! Eventually, The banks will begin getting all their crap back in the mail. Let's let them know what's it's like to get junk mail, and best of all . . . THEY'RE paying for it! Twice!
