Aah, Valentine's Day. It's a time for opening your heart and sharing your feelings. Or for some, opening your wallet and sharing your credit card. Expensive dinners for two aside, you can show that special geek that you care with a personalized gift that won't cost a fortune. Case and point (pun intended): Casetagram.
Casetagram allows you to custom design an iPhone 4/4S case using your Instagram photos. You can choose from several different designs, or pick the seasonal heart shown here, filled with your favorite photos for $35. Bonus — Castagram is running a special right now: buy two cases and get $10 off with the code VDAY2012. It's the perfect way to show your love without going completely overboard (and over budget).
