If you have an iPhone, you’ll want to check out the series of posts Erin is running over at Coupon Cravings. Today is day five of her 30 day series of money saving apps for the iPhone. Of the ones she has featured so far that I didn’t already have, CardStar is my favorite. It allows you to keep all of your store loyalty cards right on your phone! You’ll never have to go rummaging through your wallet again to find the right card. All of the bar codes and card loyalty numbers will be kept together in one place- right in your phone! Love it!
