Warehouse space opening prices

[christina.ds]

Hello dear dinostorm development team, i have been playing this lovely game since 2013, i love this game cuz i love dinosaurs obviously, so in the past when i started this game, the warehouse space opening price was always the same amount no matter how many pages/slots you unlock. But with the big update it became difficult to unlock even one more slots in warehouse because of increasing prices, so what i am asking you guys is please make it like it used to be, this way people can have as much as warehouse space they want. Thank you.
