No it doesn't!
The selling price is determined by the seller, at least in this case (and retail).
The seller chooses the price they want to sell at; they may decide that as lots of folks want something they can make a few extra bucks, rather than selling at ticket price until whateveritis is gone...
All they have to do in this situation is to invoke the immutable Law Of Supply And Demand (or Profiteers Charter as it's also known) - as everybody knows this is a fundamental law of physics and cannot be broken.
However, as the whole of economics runs on this ridiculous nonsense, what can you do? A friend of mine is Head of Global Equities for a big bank and his take is "if you can't beat 'em, join 'em - if I didn't take the money someone else will. But the whole thing is a House Built On Sand!"
