So recently offer up change their postage. $5 is USPS $7,$10 & $12 is UPS. USPS can pick up the package but what I found is it takes an extra 3 days for it to go from their facility to the UPS facility to actually get scanned into the system. Because of this I've had multiple items that had to be extended by offer up because when the USPS postman picks it up it doesn't get scammed. Recently I had something sent out that the United States postal man picked up and it never got to UPS so offer up cancel my sale, took the money back, and I have no idea where the package is...
I've seen several other users complain of this lately, due to the admin messing with the labels. It's happened to me as well. I even dropped off the package at a UPS store..wasted bc they failed to scan it in. The labels were better when they were either Fedex or USPS
