I'm sure most of the the pricing comes from the manufacturers end, but one small sprue about 1.5 X 2.5 in size with 4 little A/C units lacking any detail as all. You fold them and glue them which is easy enough but for the price I'd expect at least the exposed end to have molded vents or some detail instead of just smooth plastic. In short with some 1/4 x 3/16 styrene rod and small support leg you could churn out dozen of these for the same price. Hi-Tech Details really need to reevaluate their pricing or change their name to Hi-Price Details. I will not be buying these again.
