A friend wants you to look for a CD album with a particular song on it, you find one which you agreed to bid on for him, he doesn't have access to a computer.
Then you find another album from the same artist, an album you like, it also contains the song that your friend wants. On hearing about this album, your friend tells you not to bid on the original album, but to bid on this one, which you like, for him.
Who do you bid for, yourself or your friend?
How do you solve this?
Or isn't it a dilemma for you?
