There are at least three entities involved in the secondary market, other than the Seller. StubHub (I thought I was on the SeatGeek website when I selected the tickets), the University of Iowa, its software vendor that takes your payment (I don't recall that software vendor's name but I think it was the same vendor involved when I paid for FSU @ Pitt tickets a year ago), and then there is Google Wallet.
I bought the tickets at Pitt well in advance a year ago, and the tickets were placed in Google Wallet immediately. I am guessing that this whole system has changed for every college team, but maybe some of you have electronic tickets and can explain if it is true that the tickets don't show up in your Wallet app until a week before.
