I purchased a 2015 Prizm Intros Vinyl Andrew Luck serial #'d 3/5 before a long weekend in the Carolinas. When I returned, all packages had arrived except the Luck. Checked my purchase history, the seller hadn't shipped, so I contacted looking for an update/tracking info. The seller initially replied they needed to check on the status. The next day, it was marked shipped and I received a follow up message saying they were out of town, but were pretty sure it was shipped USPS. I asked about tracking again, but they said they weren't able to find any evidence of having shipped the card (despite marking it shipped and having sent fifteen other packages). Finally the seller said they believe they might have sent the card in the wrong mailer. Honestly, not sure what to believe... I just want to track the card down and add it to my PC.

Would appreciate help locating the card!!
