Really surprised they are still in business. I haven’t purchased a game from them in nearly a decade.
Covid aside, if you check the stores now, the majority of what they're selling isn't actually games or hardware. Mostly merch, in-game currency cards, books, gadgets, that kinda thing.
When they do sell actual games/hardware it's often to either A. clueless mothers and grandmothers who just need a Christmas present for little Timmy or B. the guys who are just buying a console, FIFA and COD when they need to and don't care enough about saving a tenner on those things.
I have a friend who's worked in one on-and-off over the years and they're (apparently) actually doing okay because of the above, they just needed to close a few stores.
