Walmart offers the KidKraft Bucket Top Mountain 56-Piece Train Set for $25.38. Opt for in-store pickup to drop it to $24.28. (Amazon has it for the same price, for Prime members only.) That's $2 under our mention from five days ago and the lowest price we could find by $10. This wooden 56-piece set includes a train, interlocking track pieces, vehicles, buildings, and scenery.
