Just to close out my experience with the pre-sales, as I could not reach u2.com by phone on the day after receiving the "here comes your code" followed by the "psych, no code for you" email, with absolutely no explanation whatsoever, I wrote U2.com via the help page, and their answer, just received, cut and pasted below, simply confirms that being a u2.com subscriber, for whatever number of years, merely places in you a lottery to get a code...and a code does not guarantee you can purchase a ticket.
So, this is what happens when a group is THIS popular, can sell out any venue they want several times over, ability to attend one of their concerts is simply not a guarantee any more, no matter how loyal and fanatical a fan you might be. This degree of supply and demand also means that they can evidently test the market to see exactly how high they can raise ticket prices until people simply can no longer afford to go...obviously, there are still enough people willing to spend $325 and up for tickets that they can defer to Tickermaster, LiveNation, etc. to proceed in this manner.
This is capitalism at its best, folks.
For the record, here is the u2.com response to the email for help....sent four days ago:
Thanks for contacting U2.com. I am pleased to be assisting you.
We apologize for our late response, we have received an unusual amount of emails.
We are diligently working to answer each email in the order received.
So sorry to hear you received an email stating you would receive a code, then received the second email retracting the first one.
Regretfully, the first email regarding the code was sent in error, then the second email was sent to correct the error made.
Registering as a Verified Fan does not guarantee you will receive a code.
The following was taken from the FAQs:
Does registering mean I get a code?
If randomly selected, you will receive a text 2-4 hours prior to the Presale or Onsale. Please note, tickets are available on a first-come, first-served basis and getting an access code does not guarantee tickets.
Our apologies for any frustration and inconvenience this has caused.
