I have three copies of Highlights Puzzlemania that are unpostable.  Some of the pages have been written on.  Between the three books, there is probably almost 2 full ones!  All three are free with one order from my shelf.

I also have a great set of like new Multiplication Flash cards from Trend.  They are also free with an order on my shelf.

See my previous thread about some math books also free with any order.

I just posted several new children's books, including Arthur's Halloween and a story of a Costa Rican Rain Forest.

Thanks for looking.
