I’ve written about the Eye-Fi several times because it’s one of the best ways to automatically backup your travel photos. Right now a 16GB wireless Eye-Fi memory card is 50% off. At $49.99 that’s a great deal for a memory card that will wirelessly send pictures you take from your camera to your laptop, smartphone, or tablet so you’ve got an instant back up. This offer is good only for the next 2 hours so if you want one, don’t wait around too long.
