Places to find records in DFW besides Doc’s

Basically I’m scavenging for ultra-rare vinyl, cassettes, CDs, etc. for my youtube channel.

I’ve found a surprising number of dirt cheap and interesting records at Goodwill. A few good ones at Montgomery Antique Mall. Some at Half Price Books (though their prices have gone up). I intend to scavenge garage sales in warmer months.

Any more off the beaten path places for NOT hyper inflated price records. It’s always the dedicated music stores that charge an arm and leg.
