If the CD costs £14 from u2.com, and £10 from other outlets, then it seems more prudent to purchase from another outlet. But if you get 2 tickets from buying the CD from u2.com you're adding a £2 charge to each ticket, to get into the presale. It is tempting but I really don't like this attempt to get me to buy it at this higher price, so I think I am going to wait till next week to get mine.
