I used to have a super fat wallet. It wasn’t filled with money; it was filled with those “buy-10-get-1-free” cards to frozen yogurt places, video rental stores, and my favorite coffee shops. But those cards are so 2005. Now, there’s Punchd, an Android and iPhone app that hosts those fun deals without the hassle of keeping a card handy. There aren’t many places participating right now (Jamba Juice and Peets are two of eight locations) but I’m sure it will catch on. Check out their Tumblr for more info.
