For all the grousing about last year's lineup (stone roses, oh, the horror), the aftermarket prices for tix right after the show sold out was solidly between $550-600/ticket.
This year with the MOR super popular artist lineup (Pharell, Outkast, Nas, A$AP, Kid Cudi, Lorde, LDR, Calvin Harris, etc...) weekend one tix going $475-525. There also doesn't seem to be as much of a gap between the weekends as in years past.
I would have expected an even more overheated market with all the popular artists, esp since it seemed like it sold out at retail faster than last year.
It's obviously better for people shut out by the ticket sale and needing to buy on aftermarket, but I'm honestly surprised prices aren't higher. There must be a massive float of tix out there.
