As one of its daily deals, Groupon offers the K'NEX Ferris Wheel
, model no. 12436, for $9.99
for shipping. That's tied with our December mention and the lowest total price we could find by $6. It features more than 400 pieces and a motor, and requires two AA batteries (not included). Deal ends May 15 at 12:59 am ET.
Need more than one? An even better deal is to add two to your cart for $19.98 and bag free shipping.
