maybe buy it cheap on Ebay, or look in a yard sale or at a new/used record/music store
I was up in Concord NH not long ago and they have a big place called Pitchfork Records. Not only did they have new and used CDs, cassettes,and DVDs but also used VHS videos, vinyl records, etc. Look around enough and you’ll find it...but that case isn’t a store that just specializes in DVD/VHS.
They add it to what is mostly a music store.
They need to become MEDIA STORES - games, movies, tv series, music, and carry related relevant merchandise, not just movie rental stores. Good point that these are the places adapting to the changes of the consumer.
