I’ve gotten a few trade offers from Chanya that seem to be considerably better than what you get from the loyalty packs. For example: 1804 LP to get 4x Natural science center. Or 3800LPs to get 5x Earth Park. The packs for these go for 2000 and 4000LPs respectively and you only get one copy. Are these offer’s too good to be true or perhaps those packs are horribly over priced for what you get?
