For the most part prices in the US are fairly consistent. But US prices can be very different than prices in foreign countries (not even including import/export fees) the difference is all based on supply and demand in the reptile markets of each country. Morphs that are very common here might not be elsewhere thereby increasing the value.

As for the difference between shows it all depends on who is vending at them, how badly they want to sell, and how big the show is.

State laws regulating reptiles can effect prices as well.
