A great commenter let me know about a fascinating new deal called TroopSwap. At first, the name made me think it was like CraigsList for military folks, but no, it is even better. It is like Groupon for military folks! (And, oh, how I love Groupon. See What's A Groupon?) Deals are good for more than one day, too, so you have a bit more time to make a decision before leaping into a purchase.
For now, TroopSwap is only available in Hampton Roads, but will be expanding to other locations soon. I can't wait until there is a location near me!
