Best of luck with your family's financial situation, I can relate. You might be better off to pick a few puzzles that you can keep, and market the rest a little more aggressively. You're not going to get even close to $1600 out of them, but $400 and keeping a half dozen of the puzzles you use most is not out of the question. Ultimately your family is more important than cubes: you can't replace family, but the cubes can be replaced with cheaper and better ones in a few months.
