If you live in Michigan then 3/21 is the day to hit Subway for a free 6 inch sandwich!
Subway restaurants of Michigan are sponsoring the Feed a Friend food drive. Bring in a canned food item to Subway on 3/21/13 and you can get a BOGO free 6″ sandwich (of equal or lesser price).
This should make for a really inexpensive lunch or dinner! (Not to mention a great way to share your stockpile!).
