Yeah, they're collectors items now so they're a bit more expensive than they used to be. You can sometimes find good deals online, I remember finding a couple deals where you could get 10 packs for 10$ but at the same time you have to be careful because lots of people like selling the "things" or "sports" series for really cheap since they aren't as popular haha. My favorite ones are the originals, aliens, and the 4 new series. Sports one is alright but "things" is pretty garbage, who wants a lamp or scissors crazy bone haha.
