The typical quantities for pre-sale tickets has been 2 tickets for arena shows and 4 tickets for outdoor stadium shows. Did you register to be a verified subscription U2.com fan member before the cut-off registration deadline of 11/12? If not, you probably won't get a U2 verified fan presale code. However, if you have a Citibank credit card, you can register as a verified fan through Citibank presale which begins tomorrow -- the Citibank verified fans are allowed up to 4 tickets. Not sure if that registration deadline has passed.
