Yes, I still buy DVD's just like I always did...
...when they go on sale for a good price.
I always buy my own copy of movies that I like, and wish to watch again, when I see them go on sale for $10 or less. The weekend after Thanksgiving is a great time to buy new-release films for $10, and older ones for $2-$7. Also, during other holidays, good DVD's can be bought for less than $10.
I DO NOT purchase, own, or use any streaming services, streaming hardware, Blu-Ray or other "high-definition" equipment, etc. Standard DVD's are more than adequate for me, and the cost difference for "high def" just isn't worth it.
