Jamba Juice is one thing because it isn't on every street corner, whereas buying Starbucks cards for people you know spend money on coffee every morning is not a bad investment. Furthermore, with Starbucks' cards, it allows you to start redeeming points for more drinks and gives you incentive to keep re-upping the value to earn those points. I get a free drink/food item every two weeks from what started as a gift card that turned into a gold card. Do I have a consumption problem? Sure. But it was a benefit to my already-shitty lifestyle and I can't complain.
