Walmart offers the K'NEX 600-Piece Ultimate Value Tub, model no. 61012, for $19. Shipping adds 97 cents, or opt for free Site-to-Store. Even with shipping, that's the lowest total price we've seen for this set and just $4 more than a 350-piece set we listed last week. This set includes bricks and instructions for building 20 different models. Sales tax is charged in most states.
