Walmart offers the Thomas the Train TrackMaster Avalanche Escape Set, model no. BDP14, for $34.20. Opt for in-store pickup to dodge the $4.97 shipping fee. That's $6 under our December mention and the lowest total price we've seen. (It's also a current price low by $12.) This TrackMaster set is over five feet long, connects with other TrackMaster playsets, and features a motorized Thomas engine, cargo car, and fossil cargo piece.
