The walking dead have done some pretty awesome campaigns to promote their new seasons and it must be hard to top each one. So how have they done it this time? They’ve done some good for the world! This is not the usual style from The Walking Dead show, but they have used an element from the show to do a good deed; blood! They set up the Blood Store in Portugal, fans could buy special merchandise for the series from the Blood Store, but the currency is not metal and paper; it’s blood! The “customers” if you could call them that, donated blood to buy the products, the more they could donate the better the item. It increased donations by 517%! Blood donation is something everyone could need at some time in their life, but blood banks are running low – according to reports here in the UK anyway – so any way they can increase donations is a brilliant idea.
