Shop Kmart for buy one, get one for $1 on shoes for the whole family! Look for lots of great Frozen shoes and boots from Bongo! Shipping is free on orders over $59, or if you have a store nearby ship it there free.
As a deal idea, you can get Frozen Scuff Slippers for $12.99, and add a second pair for $1 or get a pair of TMNT slippers for the little guy for $1 instead. That comes out to $7 a pair!
