Toys"R"Us via eBay offers the Imaginarium 100-Piece Mountain Rock Train Set for $99.99. Opt for in-store pickup to avoid the $19.99 shipping fee. That's tied with our March mention and the lowest price we could find by $20. It features 23 feet of track, lights and sounds, a play table with storage drawer, eight trains, two vehicles, three traffic signs, a fueling station, and five cargo bundles.
