Hi. I just listed a $50 Amazon gift card on your site for $48. I listed it with instant delivery so I put the code into gameflip. Then, after I listed it, I realized it was in the wrong category. Noticing this, I deleted the listing and attempted to make a new one. But this time, when I tried to turn on instant delivery, it says that the gift code already exists for a digital item. So now, instant delivery isn’t an option. Any help with this would be appreciated!
If the code haven’t been used already you still can sell it through autodelivery. That message only appears because you already put that code in another listing. If you want to add it in another, just type something else at the end. Eg: “XXXX-XXXX-XXXX This is the code.” So it would be like if you added a new code so it won’t say it already exists.
Hope, you can understand me. 
I gotcha. Thanks!
