Amazon has a great deal on the K’Nex Nintendo Mario and Diddy Kongs Fire Challenge Building Set for only $21.99.  It retails on Amazon for $64.99 but can be found at Walmart for $43.97 as a rollback.
This is on my youngest son’s list and he loves Mario Kart. This would be perfect to put together on a snow day!
