ATTENTION Resellers!!!! DO NOT under any circumstances post any part of a Digital Movie/TV Code in your listing. Yes you can put in your listing that you include the code or show a part of the insert that shows that it's the digital insert but again NEVER the code itself. The reason is because if you do show all of it or most of it anyone can grab it or figure it out and redeem it. Then if you sell the listing and it exclaims that the Digital is good and the Buyer finds out it's been redeemed then they can return it or you will be asked to give a partial refund. I have seen an appalling amount of Sellers, mainly Sellers with under 100 reviews, post the code in it's entirety. I typically message them to tell them not to. I don't think eBay makes any mention of not showing codes in your listing.
Also while we're on the subject, after messaging some of these Sellers to tell them not to do this the most common question I get asked is how to check to see if the code is still good without redeeming it. Well it's simple. Visit the site the code redeems to and type it in, don't add an e-mail or make a login, hit submit and typically on another screen it will tell you if it's still valid and where it can redeem to.
Also MOST Digital Codes DO NOT expire. Despite what the insert says is the expiration most of these redeem 10-15 years after they were issued. Although Warner Bros have changed theirs. If you have a WB code with a listing you made a year ago, chances are it's expired, even inside a Brand New item.
If you have anything else to add please do so but I just wanted Sellers to understand that these Digital Codes can change the value of your listing, drastically even. So you need to protect them, even the DVD ones.
