Had a priority 4 day domestic order (very low profile letter mail not worried about seizure) not turn up after 10 days and asked the vendor for tracking and he provided. He honestly shipped it when he said he did, 10 days ago, but after being picked up it has been stuck as 'In transit to destination' with no updates other than that it was picked up, went into transit 10 days ago, and now nothing. How long have you ever had an order be in transit, what might this be?
Yes, I've had packs not update for up to 2 weeks. Sometimes USPS just loses your pack and it doesn't get updated. I would wait until the 2 week mark and then ask for a reship. Don't forget to extend your escrow timer with a dispute.
