The 3/5 cars always ring up 1.67, 1.67, 1.66, so these will probably be 1.67, 1.67, .01.
Last time I bought some, my son wanted a Mad Maverick, so I also grabbed a Woodies and Panels white 55 Ford. They were currently having the buy one, get second at half price sale. They guy behind the register told me that I could grab another one to get 3 for $5. I told him that the first one would ring up $1.67, and the second one would ring up .83. He was shocked when I was right.
