Print your own local "Cash Register Receipt" coupons

I looked up the company the does the coupons on the back of the cash register receipts at my grocery store, and discovered that you can do a zip code search and print out coupons for businesses in the general area that might not have advertised at your particular store. (It's also good if you've seen the coupon on the receipt, but didn't save it.)

My search found 985 coupons within 50 miles of downtown Houston (77001)

15% off Denny's
Free Whopper or Croissanwich at Burger King
Free Quarter Pounder w/ Cheese at McDonald's
$20 Firestone Oil Change
$17 NTB Oil Change

as well as coupons for cleaners, more oil changes, hair cuts, mufflers, DONUTS, more restaurants, nails, and just a pile more.

Some example coupons are below.

I figure if I had never heard that you could do this, a lot of people haven't. Heck, to ME this is FP news (To the more experienced, mebbie not so much :p )
