Change an IntValue just for a player

Hello! I just started working on a game and I got stuck at this part. I want to make a shop with upgrades but the thing is that after you buy something the price will grow up.

I really don’t know how to change an IntValue just for a player. After somebody buys an upgrade the price goes up for everyone.

This may be a question with a simple answer but I can’t get it.

Keep the value object under a container specific to a certain player, for e.g the player itself and change its value through a LocalScript so the value doesn’t replicate back to the server.
