So I bought an item last Tuesday seller didn’t ship till Thursday
Didn’t say it was shipped until I messaged seller and they contacted the post office then it updated
Since then it’s been saying it’s waiting till usps gets the item but seller says they dropped it off.
Anyone know how long until I see it start moving and get updates.
They also mentioned the place they drop it off at takes a day or 2 for them to confirm shipments on the weekends but by the time they confirm it the package is already moving but still nothing
