Check Your Receipts...

...but not just for pricing mistakes. Many receipts have coupons or surveys on the bottom. I'm not talking about the receipts that offer a sweepstakes entry or a chance to win $$, but the ones that offer you a freebie for completing a simple survey.

Take the survey and get a code for something free. The surveys are very quick and painless! Some are online and others are done by phone. Here are some that I've received:

Albertsons - Free French Bread
Sonic - Free Route 44 soda (Thanks Angie!)
Wingers - Free Asphalt Pie
PetSmart - $2 off coupon
PetCo - $ off coupon

UPDATES (Thanks Steph!)
Arby's - Free Beef & Cheddar or Regular Roast Beef
Burger King - Free Whopper w/ purchase of fries and drink

Let me know of any other stores that do this and I will add them to the list!
