Too expensive

I dont understand why this games in app purchases are so expensive. Its a digital card game and I cant do anything with the cards other than play matches that either take way too long or are over in 5 turns. The other week they sold a small amount of stuff for $70. Thats more than an entire RL video game costs when its brand new. Come on people, this is crazy...everything should be at least 5x cheaper...
