I was talking about Papa Murphy’s with a friend just last night. I found this info on Money Saving Mom’s website:
If you have unlimited texting on your cell phone, you can get a coupon for a free medium pizza from Papa Murphy's when you text MURPHY to 686868. The coupon should arrive within an hour of sending the text and is good through June 30, 2009. You just show the coupon to the cashier when you checkout in order to redeem it.
