U2 in Montreal,Canada !!!! EMERGENCY !!!!

Hi,
I looked in HMV today, adn I checked out a book where they state all the
new albums come out for the year. And of course, I checked the U2
section (comes out november 3, checked to make sure). Anyways, It not
only had U2 best of (limited edition), but it also said that a double
live album is coming out the same day !!! Can someone explain this to
me.
Also, how much is the limited best of, (canadian currency), and is the
b-sides packaged along with it. And if there is a double-live album ,
how much is it ?? Please get back to me, I going crazy. The HMV staff
can't even give me a straight answer. I think there getting fed up of
me, and I don't even know if there going to let me in the store, just
kidding. !!! Anyways, please get back to me.
