Best Choice Products via Walmart offers its Best Choice Products 100-Piece Wooden Triple Loop Railway Set for $37.99 with free shipping. That's the lowest price we could find by $13, although we saw it for $3 less last July. The set includes railway tracks, bridges, buildings, traffic signs, magnetized train engines, city vehicles, trees, and pedestrian figurines. It's compatible with Thomas and Friends, Chuggington, Brio, and other wooden train sets.
