Waigo is the main agent for Yokomo & Tamiya, and they are protecting their dealers outside. The prices listed in Waigo are (maybe) for references only, it is up to the dealer outside to sell it cheaper or more expensive. If they are selling the car hundred dollar cheaper than the dealers, eg., Uncle Chan will be eating "west-north wind", everybody will just go and get thier things from the main agent. The same goes to World Model, City Hobby & Jet Hobby, they don't normally give discount in thier shop, they are expecting you to get their products from their dealers.
Am I right, Mr Mars??
