I have just finished a used 1000 piece puzzle that I received with 2 pieces missing. It's really cute, and I will post a pic of it if anyone is interested in a possible swap, each side paying their own shipping.
I might add, too, that shipping is far less (can be done via media mail in the US) if the puzzle pieces are removed from the clumsy box, and the picture of the puzzle, including the number of pieces, put in a sealed plastic bag for shipping.
Would anyone in the US be interested in that sort of swap?
