Kellogg's #TweetShop - Pay with a Tweet

Kellogg's are claiming a world's first with a pop-up shop in London where you pay with a tweet.  (Kellogg are a client of the agency I work for, but I'm not involved in this campaign)

It was announced this morning with this Tweet:

World's first Tweet Shop opens today to launch new Cracker Crisps. 13 Meard Street London. 1 tweet= free box #tweetshop twitter.com/KelloggsUK/sta…

In the name of research I went down at lunchtime to get some - here's the outside of the shop:

& a packet of the Special K Cracker Crisps

& the Tweet I sent to get my free packet.

At the new @kelloggsuk #TweetShop in Meard Street, Soho 1 tweet gets you 1 pack instagr.am/p/P_6SYHMgvJ/
