We've seen a number of somewhat innocent (and equally wily) hacks that save the little man a dime or two, but never quite so literally as this one. CoinStar machines -- best known for charging a whopping nine percent or so for the convenience of counting our coins for us -- have apparently been outsmarted, making the green machine convert your coins to dollars gratis (without going through the process of getting a gift card).

Update: Upon reflection, we probably shouldn't go into the gory details of how its done -- but it's nothing so mind-blowing (except for its potential illegality -- you wouldn't tamper with an ATM, would you? This ain't much different.). Or you can, you know, do the right thing and just take an Amazon gift cert and not have to live a look-over-your-shoulder kind of lifestyle.
