Know any good record stores?

I’ve been to a few different places with varying success In finding more modern cds. I’ve been to the cave which is very disorganized and it’s like just shifting through endless rows of mismatched unheard of bands and records. I’m looking for more metal and maybe even some subgenres like shoegaze or Memphis rap. I’ve been thinking about just buying the specific albums online for dirt cheap but I also can’t find a trust worthy site for that either. Any help is really appreciated I am looking for cd’s and maybe Cassettes although I’m sure most of the cassettes are older.
