Starbucks started expanding their "Pick of the Week" program in the US a few months ago, and their Canadian locations are following suit. Starting this week, the Pick of the Week cards (which have previously offered free music downloads from the iTunes music store) will feature free iPhone app downloads as well!
Each week, there will be a new song or app featured on the cards. Grab your card in stores, and then use the code on the back to get your free download. You will need an iTunes store login to redeem your code.
