Gilt Groupe, our favorite sample sale website recently launched an iPhone app. I haven’t gotten the chance to give it a run during the peak hour of 12pm but the interface leads me to believe it’s a solid offering. Six taps is all it takes to get from the shop to a completed purchase, making things much more accessible and efficient. Now, you won’t have to hide the web browser at work. Instead, you can just fire this app up and shop from the palm of your hand.
