Player prices are way too much

I recently got back into Animal jam and I’ve noticed that a lot of the time when players are selling items, they’re about 800 diamonds each item. I extremely confused on why this is, it feels like animal jam has just turned into a pay to win game. I just don’t understand why they price their items so high even if they’re rare, like I understand 100 diamonds, but 800? Quick and easy diamonds I guess?
