I send the code before people mark received. I'm just getting scammed of giving the codes out and people not marking received and just leaving the message hang. I put that out there so people know they must be online and interactive if they want the code.
Your cover by listia by showing on email you sent the code. We have 3 days to mark received before you can dispute that. It just better for you to show you did your part and sent the code. That's how it is set up by listia. No product no credits. Have never been burned doing it that way by codes on email or actual mail
I have been sending codes? You can ask every single person who has gotten a code from me. I send the code , I click "I sent the item" and I wait for the person to click they mark received. You can't mark received until I press the "I sent" button. You can look at my feedback. You can message people who won my auctions. If you think I'm gonna scam you out, then don't get something from me. But I have an 100% positive feedback streak.
