WHY IS EVERYTHING THAT IS RELATED TO TRADING CARDS SO EXPENSIVE?

Like seriously…everything related to trading cards or collecting cards is so expensive!! First, Pokémon cards are so expensive. People are selling them and paying hundreds to thousands of dollars for some reason! And K-pop photo cards, people also sell em for so much! Especially the digital ones!! Who has that kind of money? How?

CARDS IS THE WORST MONEY HUNGRY INTEREST EVER!!

People complaining about consoles costing around $700 and more!

BUT This is something people should be fighting over instead, not consoles!. Who tf has the money to spend $700 or around that on digital cards!

On trading cards!!
