I have purchased some blu ray disc that have the blu ray disc,the dvd , and the digital copy. I don't want the dvd or digital copy so I sell them on ebay . I put them in a plastic case and I keep the Original Blu ray case. If it's a Disney movie I sell the disney reward points with the Digital copy. To my surprise I get all of my money back for what I paid for the blu ray. A few times I've made a profit. I purchased UP for $19.99. I sold the DVD and Digital copy for a total of $23. Each was sold separately. I still don't get why someone would pay $12 for just a dvd or $10 for just a digital copy on ebay
