There used to be CD stores and every major outlet had some assortment of CDs. Then they all went online and you could order CDs from all sorts of quant and off colour websites. But that's all gone now, or have escaped me. How do people get there CDs today?
Record stores > thrift stores > online I spend couple hours searching on record stores and thrift stores, but if I want something specific that I couldn't find anywhere else I buy online.
Hell yes, boost the record stores, send them as much business as your personal recommendations to family, friends, acquaintances and strangers can can. If they fail, where else am I going to be able to find cassettes?
