Our WalMart has never had trains but they do have a model department that has the Testor's starter airbrush set that comes with the propellant can and some paint. Like I said, it's about $25 and I wouldn't buy one when the Badger is available for the same price. They do sometimes have a good selection of diecast HO scale vehicles and will periodically put them on sale for 50 cents each. Way better deal than buyig them off e-bay for $5 plus shipping.
