Thank you kindly for pointing that out! There are constant things that are being missed, such as small things like that.
As for your question, alas we cannot prevent higher markups, and it is highly likely that that will remain for high demand shows. However, as it says in the FAQ (and what I said in my first post), odds are not out of your favor that tickets will be below face value as the event nears. Simple supply and demand. In fact we recommend that people go a few days before and do some exploring to find some great deals (an echo of my P.S. above).
