Trade at Brick and Mortar Stores
I used to trade my DVDs for store credit at Babbages at the mall. There was this one time, however, where I brought in my stack of unwanted Christmas DVDs, all of them still wrapped in the cellophane. The clerk wouldn't take my DVDs. He wasn't allowed to take DVDs still wrapped in cellophane, cause I might have stolen them from Suncoast Video.
"So what's stopping me from stealing some DVDs from Suncoast and taking off the cellophane before I bring them here next time?" I asked the clerk. "I don't know." he said. And that was that. The Lesson: Call ahead and ask if you have to remove the cellophane before you try and trade in your DVDs for store credit.
