The Walking Dead Pop-Up Store Requires You Pay with Your Blood

To promote season four of The Walking Dead, FOX Portugal came up with the simplest of concepts: if you want blood, folks, then you gotta give it. That's right, they opened a pop-up store in which blood serves as currency. It's the first of its kind in the world.

All you have to do is walk in and bare your forearm. The attendant produces a needle, fills a vial and sends it to the Portugese National Blood Bank Institute. You walk away with brand new, uber-gory merch and someone, somewhere, gets a much-needed transfusion. The more blood you give, the more goods you score.

The store attracted customers at the rate of a World War Z zombie swarm. Blood donations reportedly increased by 571 percent in comparison with last year, and 67 percent of those giving the needle the green light were first-time donors. At the same time, The Walking Dead enjoyed a 17 percent boost in ratings.

Given such overwhelmingly successful statistics, additional incarnations of the store are now set to pop-up in nations all over the world, including The Netherlands, Turkey, Brazil, Argentina, Columbia and the United States.

The Walking Dead Blood Store was created in conjunction with creative agency Torke + CC, whose motto reads "handcrafted ideas to rule the world."
