I purchased a PS5 disc version to save me money.

It allows me to buy a newly released game for £60, complete it within a week and sell it on for £40. Also allows me to buy cheap second hand games.

But saying that... I am getting lazy to the point where I don't want to play a game if it means having to get off my seat to change the disc.

I'd also like to add that I purchased the disc version before knowing Sony were going to do PS extra. I'm sure the next generation of consoles will not give you an option for a disc drive for this reason - there won't be a demand.
