I'm not quite sure why as the prices are remaining at RRP but IMO PS5 availability is being manipulated - I understand to an extent the retailers releasing stock in blocks of smaller quantities to prevent their web-sites being overloaded and to try and prevent scalpers getting the lot in one go, etc. but there is a lot more quantity coming into the UK that seems to just sit around for weeks or even months on end before moving.
I said in the PS5 thread, I feel the PS5 situation is self inflicted by the retailers, I think if they just opened up pre orders round the clock after the initial surge it would calm down. The issue is though I think a lot of people are not very patient, and not everyone is like me not minding waiting months for delivery. Their websites get overloaded because they forcing everyone on to them at the same time.
