Pepsi has been doing this every Tuesday since the beginning of summer if I remember correctly. But it looks like they're done giving out codes for the day, so you'll have to try again next Tuesday. Unfortunately though, Amazon rarely sales popular albums for $0.99
I decided not to buy Regina's album when it came out because I had so much other music, and I had sort of gotten over her, but now I thought "why not"?
Now I have the album, and Regina gets paid as she deserves to be. (otherwise I wouldve borrowed a library copy in few months.,.....)
