I would assume- or I guess, more accurately, hope- that what it means is that the tickets that are part of the $250 presale are the ones that will be more expensive on general sale.
But the thing is, I don't think this is really a deal if one really only cares about seeing Small Mouth Sounds. These are functionally at least $400 tickets once you factor in the mandatory Downstate ticket purchase. If you're unwilling or unable to see Downstate, you're not getting a deal, really.
