Macy's credit cards usually have a 20% discount on purchases. I pay with the Macy's card, then while still at the register, I immediately pay off the charge with my debit card. I just got 20% off my purchase and I never get a credit card bill. - this also works with JCP and kohl's cards.
Most tinfoil and saran wrap boxes have little push-in tabs on the sides. If you push them in, the roll won't fall out when you try to rip out a sheet of it.
Keep a list of all of the credit card phone numbers (1-800) in your cell phone. This way, if your wallet is ever lost, you can call them immediately to have them disabled.
