Kraft has an awesome promotion going on where you can save some money and help others at the same time. Head over to this page and you can print out a coupon for $5 off the purchase of 5 Kraft cheese or dairy products (6 oz. or larger, unless otherwise specified). After you redeem your coupon, Kraft will donate 5 meals to Feed America.
If you have a Publix nearby, and need sour cream, Publix has Breakstone Sour Cream on sale this week for 2 for $2. You can purchase 5 for $5 and then use your $5 off coupon making them free.
(Thanks MojoSavings for the sour cream tip)
