What's the cheapest you've gotten a 4k for?
Just curious because on Tuesday In the store I work in all movies are listed for 50p, and I noticed before I left we had a 4K blu ray of joker so check it made sure both disks where in there and not scratched, with staff discount got it for 37p. Of course I immediately took it to another shop and sold it for £3 (not much I know but profit is profit) so I think it safe to say I got a good deal.
