When I put this together I was convinced it was under $10, but tagging all the bits in the picture makes me think I spent closer to $15. Oops. Well, Rebecca and I had too much fun putting it all together, and since we split most of the bits in half or such, it was for us as much as our swap partner. If we'd left out the paint we probably could have gotten it under $10 easy, but we have gallons of washable kids paint, and giving people presents is just too much fun to pass up.
We haven't gotten our box yet, but I'm sure we will, and then it will be more fun all over again.
