Expansion packs cheaper

I do not think expansion packs should be free but i think they should be more affordable. 40 dollars for 1 expansion pack is CRAZY. As a teen i cant imagine how people have all of them. There are a lot of sales but its still kinda pricey. I also feel like there arent any updates for base game. Only little things but nothing big. And the furniture and cas packs are also crazy. Like who in their right mind  is paying 5 dollars for 5 cas items?
