A few cheap card games I stumbled across. Good light or filler games for a number of people. Fair to good reviews, but not much to lose as around $10.
Hanabi $12.00
Saboteur $10.23
Exploding Kittens NSFW Edition $9.08 (for whatever reason cheaper on a different listing)
Let me know if you come across anything else cheap and I can update.
Exploding kittens is actually a boring game with very limited replayability. I don't know why it was such a kickstarter success. There's not much to the game and it's like a glorified go-fish.
