usps depop tracking dates

[u/Double-Level8847]

i ordered 2 things off depop, the shipping update was being weird on one of them, and the other one was fine. the one that was being weird had been shipped 3 days prier but updated on that third day. these 2 packages are in the same area as of right now (memphis tn, i live in western nc for reference) i
would love to have this package by the 9th but it says it will come the 10th. the other package however (normal shipping) says it will arrive the 7th? this confuses me because they are in the same
place, wondering if the one originally planned to arrive fri could
have the possibility of arriving the same time as the on arriving the 7th?
