Riddle Me This - What is the Woolworths Giftset (and why is it so expensive)?

Taking a brief break from the Batman Forever Merchandise Reviews to introduce Riddle Me This - a series covering a variety of Batman Forever topics. 

First up I'm looking at the Woolworths Giftset for the Acclaim Batman Forever game - a bizarrely expensive box containing the game and other merchandise that goes for £500 - £900 on eBay! 

As a bonus I've included a capture of the Making of the Video Game VHS that was included in the set.
