I’ve also seen a few posts from members here, talking about buying Red Hat install discs at Best Buy.
I'm one who bought RedHat 4 and 5 at Best Buy, and a bit later SuSE 9. Mostly to get the install media and manuals, in those days of 2400 baud modems downloading a large amount of data was pretty expensive (and slow).
Count me as another Turbo C owner too. (and Paradox)
