If you wait it will end up in your local charity shop. Some nice folks buy the DVD/BR then rip them and then donate the disc to their favourite charity. People donate absolutely new stuff, get an unwanted present? donate it. Too embarrassed to send something back or don't want the hassle/aggro? donate it.
I volunteer in a BHF charity shop so I know. Don't wait too long though, it isn't clear how long it will be before it isn't worth stocking DVD's, old games and CD's any more. Though some hip youngsters will go through the CD's looking for interesting old stuff they don't know about.
