Similar to This deal posted back in August. A few Clementoni 1000pc puzzles are on sale for $10 each, featuring popular licenses such as Game of Thrones, Stranger Things, DC and Marvel. Price is about right for a cheap KK or similar.

Ravensburger Escape Puzzle Kid's Amusement Park Pligh $12
Review
They actually have some Ravensburger Escape Jigsaw puzzles as well, like the one linked above. They had different ones in-store at my local to what they have online so I haven't tried to link them all.
These escape puzzles are a bit different to your run of the mill jigsaw puzzle. The image on the jigsaw is a little different to the image on the box. Based on the differences you find, you need to solve 6 puzzles to "escape" the puzzle. I quite liked the puzzles but my wife really wasn't a fan. She was actually quite disappointed in the puzzles but I don't think puzzles are her thing. In any case, once you solve the puzzle once, you can't really solve it again, so keep that in mind. You can of course redo the puzzle as many times as you like.
After we did the Amusement Park one, I went back and bought a couple more. I think for $12 they are pretty good. My wife let me buy some more so the puzzles didn't put her off getting more.
Now I need a frame.
