As much as you may be upset, just as ticket scalpers gouge the average music or sports fan, it comes down to simple supply and demand. If the prices seem too outrageous, in time, the prices will fall especially if the demand is not there. This has been going on since Cabbage Patch dolls, Furbys, Beanie Babies, etc. What people ASK for an item and what they actually GET are 2 totally different amounts. Just so you know, I don't sell WDW items, lest you think I'm one of them, but it's capitalism.
However, in several jurisdictions, scapling a ticket (selling it for more than a set amount above face value) is illegal.
