Second hand minefield

Buying cheap games for the PlayStation 4 seems to be subject to a few more pitfalls than it is for the Xbox One. Clearly the PlayStation 4 sold a lot more units that the Xbox One and presumably it shifted a correspondingly higher number of games. This seems to result in an increased chance of ending up with either an imported game, or one originally intended to be part of a bundle. Or in some cases both. 

So far I have bought about 10 games for the PlayStation 4 from a variety of sources and three of them have turned out to be something other than the UK retail version I assumed I was buying. I have never encountered this issue when buying Xbox One games. I did once buy an Xbox 360 game from a charity shop with Arabic text on the sleeve, but it was only £1 and I knew what I was buying. Yes, the games I have received work and they are in English, but that's not the point. The issue that, due to the ongoing lock-down/pandemic, I am obliged to buy games online and I am not receiving the exact specification I am expecting.
