National Record Mart was the dominant seller in Youngstown, Ohio where I grew up and developed my LP habit, with a big store in every mall and shopping plaza. I'd have done anything for a PT job there as a teen, but there was no way.
NRM had great selection but charged top dollar. I loved the ritual in spite of the venue. There were no alternative, independent outlets in Y-town in the 1970's.
After starting college, I found some better options, including an excellent independent in Butler, PA which undersold NRM by better than a buck per album. I also scored a ton of LP's thru record club memberships. And, yeah Brad, lots of cheaper cutouts.
When we moved to Columbus, Ohio, in 1982 I started going to Record and Tape Outlet, a local chain with better service and decent prices. I was loyal to them until the LP to CD transition.
As a listener, I'm still stuck in that era. Listened to Jackson Browne's Saturate Before Using and For Everyman yesterday, as well as CTI Summer Jazz, an all-star ensemble featuring George Benson, Esther Phillips and other greats. Today I started with Nirvana's Nevermind and REM's Murmur.
