Amazon offers the Super Spirograph 75-Piece 50th Anniversary Jumbo Kit for $19.99 with free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, it adds $6.90.) That's $20 off and the lowest total price we could find. It includes Spiro-putty, two design racks, 22 wheels, three pens, pads of paper, and instructions.
