These days, better records are on their way to the dump than to the thrift store. A local junk removal service runs a "garage sale" every Saturday and the records I have found there over the last year have beat the pants off of anything I've found at thrift stores in the last 5. Experimental folk psych, blues electronica, stuff you just never see. Imagine if he didn't bother and just sent everything to the dump. Maybe thrift stores do still get these kind of records donated, but I'm not likely to ever get a chance to buy them.
