Bought a lego set from a thrift shop the other day. It was a big expensive set that was half price but didn't come with the box, all the pieces were in a tote. Of course, when I got it home I started counting the pieces to make sure nothing was missing.
The first piece I started counting I found all of them and an extra. Then another. Then another. Until 100 pieces became 200. Lucky me!
I got 2 big expensive lego sets for the price of half of one! Nothing is missing so far, so very good find.
