well, i think its pointless, eventhough ive been doing it for a while, every so often.
"Imagine the frustration of credit card companies when they have to spend millions of dollars every year on first-class postage just to open up an envelope and find Pizza Hut coupons inside. The envelopes are intended to be used for "BUSINESS REPLY MAIL," and so use them for their intended purpose. You're sending them valuable money-saving coupons which could mean big savings to credit card companies, and it makes good business sense to use them. Consider it a reply to their business proposition with a business proposition of your own: 35 cents off a large, one-topping pizza."
great shit though
