Yes the sound exchange would buy many of them but keep in mind they only buy movies they either dont have or are short on stock. If your titles are newer then they probably have those. They seem to buy older titles more. Good luck.
Try contacting them or better go in person I'm shure they can guide you on what its best for you,good luck.
Take them there, in batches that they can handle in one day, as their offer is only good the day they make it. Call and ask, but I'm guessing they'll want about 500 max a day, unless they make some sort of arrangement.
