I worked in a record store in 1978 and list price for a single LP was $8.98; my store sold that lp for $5.49. CD's were introduced in 1982 with a list price of something like $15.98 or $16.98. Can't tell you what they sold for, 'coz I didn't get a CD player until the early 90's.
I do remember killing some time in a mall in Minneapolis (not the Mall of America) and stopping in to a stereo shop there when CD's were new. The salesman played 'Dark Side of the Moon' on a Sony CDP and it was amazing how you could stop and start the music with a touch of a button on the remote. We now take it for granted, but lp's never did that. The sound quality on that Sony was crap, BTW.
