Alternatives to values Inside the player?

I’m making a shop buying system where if you buy an item it appears on a table. and I can’t think of anyway else for the game to remember if the player bought the item. and before i script everything into place I just think about the organization of the player. Everything in the will be clogged up and even if i place a folder into the player then place the values in there it still would be clogged. Is there any alternatives or do I just have to find a way to organize it properly?

Place the values inside of a folder?
Or you can try attributes.

Also why are you trying to store this info inside of the player,
wouldn’t datastore be easier?
