Ryan P sent us a nice tip about using Coinstar units to turn your spare change into iTunes apps. You've seen Coinstar at the grocery store before -- you throw your spare change in there, and then it spits out a receipt you can take to the service counter for cash (minus a little off the top for the counting). But Ryan told us Coinstar now offers gift certificates instead of cash, if you want, minus the coin counting charge.
And one of those certificates can be used at the iTunes store, which means you can throw your coins in, and instead of paying Coinstar to count them, get the full value of your change in an iTunes card. And since apps on the App Store are so cheap, you can use your former quarters and dimes to pick up some terrific apps (may we recommend Sketches, or maybe Pennies -- since you're so coin-conscious anyway). And considering that the amount Coinstar takes out is almost 9%, putting the money in an iTunes card (if you're going to buy the apps anyway) can be a nice chunk of change.
