Walmart offers this 50-Piece Train Set with 2-in-1 Activity Table, model no. 38390, for $37. Opt for in-store pickup to avoid the $5.97 shipping charge. That's tied with our September mention as the best price we've seen. (It's a current low by $20.) It includes a table with a reversible chalkboard top, cloth storage bin, and 50 pieces of track, bridge, and accessories.
