This is a snazzy add-on for Instagram brands, allowing their followers to shop directly via the channel. When a user "taps" on a brand's photo, the user receives an email w. the product featured and ready to buy. I've used it a few times and it's fairly seamless. You can also search #liketkit on Instagram (close to 410k shoppable photos).
Note: this was before Instagram started testing deep links via their new ad units.
