Library. I order DVDs to my local library all the time. Maybe your library system is terrible, but if it isn't you certainly can do this. There are hundreds a big wide release films with, effectively, are only available on DVD from a library (legally).

Bonus when I go I can still get that browsing the aisle experience like in an old video store (but in this case I am lucky, my local library has a large DVD / Blu-ray collection to browse)
