Do you still buy DVD or Blu-ray discs today?

Yes I do. I think with a number of providers limiting bandwidth the cost is going to be the same if not more. I am in an area that I can only use satalite, and limited to 10 gig as basic bandwidth. Each gig over 10 is extra. These providers see a profit in limiting the bandwidth. It is not cost effective in my situation to stream movies but to buy them.
