Adjusting the price of goods based on supply and demand. Pretty neat concept. Think it’ll take off? 
“The prices will fluctuate in $.25 cent increments, but will most likely plateau at a $2 change in either direction.”
Still pretty cool I guess.
Same concept can be applied to movies at the Cinema.
I mean prices on DVDs fluctuate.
