Cheapest price according to the camels. Looks like it has been cheaper at other stores, notably Kmart and Target cleared them for $40 and $29 respectively. Would have been nice to get it for $29 but they are unobtainable now so $42.49 will have to do.
Edit: Available again but backorder only.
Great set, amazing how Thomas and Percy communicate with each other and stop and go together. The tracks are a bit badly designed and the trains fall off a bit to often. Needs a lot of floor space.
