I don't think the price on this set goes much lower. I got it for the same price (sans shipping) at a TJ Maxx a couple Christmases ago. Costco had a similar-looking set this winter that got as low as $40 shipped, but it was unbranded. (Kirkland blocks?)
My 3-year-old uses these blocks to make towers, racetracks, homes for Hex Bugs. I like putting them back in the box Tetris style when playtime is done. Guess that's where the math comes in. The set fits squarely into its storage box -- the only bit of filler when you open the package is a tiny bit of styrofoam. The $5 shipping is a steal.
Hard to tell if it includes any of the long pieces.
There are two long pieces, the length of the shorter side of the box -- about 12 inches.
The set is imported but I can't remember where from. Ain't getting out of bed to check.
