Where to buy movies?

Hey all,

I'm looking for a place to buy movies in the Willowbrook/Copperfield/Cypress/Jersey Village/Katy area.

I love classic movies (pre-1970's) but I'm continually let down by what's available at Best Buy, Target, Walmart, and Barnes and Noble.

I know the Alamo Drafthouse has kind of become a beacon for cinephiles wanting to see classic movies in the theater, but what about DVD and Blu-Ray?

Movie Exchange on 1960 used to be a little oasis in the desert, but they've apparently shut down for good thanks to the pandemic. Was that our last hope?

Thanks for your help.
