If you visit a Starbucks this weekend, look around for their stack of iTunes ‘free’ cards. They can be found next to the cash registers, coffee pickup area or in the cream/sugar area. The cards generally change weekly. Most often, the card is good for a single song which you can download through iTunes without being charged. Sometimes, like this week, the card has a code that will get you a app for free.
In this case, the card will save you a few dollars as it will get you a copy of the universal app SnapSeed. A very nice iPad photo editing app. Availability is as long as their inventory lasts. Also, the card does expire so if you want to get this great editor for free get into your local Starbucks!
