Why does it say it's hundreds of pounds worth of stuff for a pound? Could you please explain how it works?
Humble Monte Cook Bundle

Well, if you were to buy all of the books individually in hard copy, it costs "hundreds of pounds" - with the bundle, you're getting the PDFs of those books for as much as you want to pay, with a minimum of 1 pound. You can choose to pay more, and I think if you choose to pay a certain amount, there's additional content, but I don't know what that is.

Not long to go now, only just thought to post here - it's his Cypher system plus his Ptolus books for that and 5e, the Strange, lots of other stuff.
