Walmart offers the Thomas the Train: TrackMaster Windmill Starter Set, model no BGX97, for $12.12. Opt for in-store pickup to dodge the $4.97 shipping fee. (Amazon offers it for the same with free shipping for Prime members.) That's tied with our mention from two weeks ago and the lowest total price we could find now by $10. It includes a motorized Thomas, track layout, and windmill; and is compatible with all TrackMaster sets.
