It's all good, guys! I've got you covered!
This is why I bought six copies of
19, seven copies of
21, and five copies of
25!
(Plus three copies of
Live at the Royal Albert Hall and six of "Skyfall"!) But that's because I collect them and have every edition. But then I just burned CDs for my car because I don't want to take my actual copies of the CDs out of my house, and that way I could combine all of the bonus tracks and stuff onto one CD per album.
Don't feel bad, OneAndOnly.... I used to do that, too! But then I felt bad, so I went and bought all the albums I downloaded off of library CDs, and I haven't done that since!
EDIT: I didn't see Cockney's post, but it's the same for me, except I bought every edition of the CDs.
the first Adele CD I bought was 25, and I was gifted the Royal Albert Hall DVD.
I think what cost her was the attention the Carpool Karaoke thing has gotten over the past year. 
This song's longevity is INSANE. 
Sorry I misunderstood. I agree with you and OAO's addition on the subject.
I do go overboard now like Addict and buy the physical single cds and promos
This probably means that she'll hold off on releasing "Water Under the Bridge" for a while, too. I hope they release that by October.
