A song we sang as kids in the 1950s also addressed the issue of unit pricing:

Heigh ho, Heigh ho!
We're off to the burlesque show.
We pay two bits to see two tits.
Heigh ho, Heigh ho!

Two bits is 25 cents American. The 25 cents of the 1950s is probably worth $3 or $4 today. Even allowing for inflation, on a cost per unit basis it's stil less than Skipy is paying.
