"USPS awaiting item" when I physically dropped it off at the post office 4 days ago

I printed the USPS shipping label and appended to the package on Sunday 5/21, then physically dropped it off at the Post Office around noon on Monday 5/22. It's now Thursday and the USPS tracking page hasn't been updated saying that "USPS awaiting item". I had actually dropped off another package after hours that same day in their drop box and oddly enough that one is showing movement. Both were shipped with labels generated directly through eBay, both USPS Parcel Select Ground. I visited the Post Office yesterday and she told me it's possible that the package was loaded on the truck without being scanned in, but that it might be scanned in at the distribution facility though after about 4 business days, I'm starting to become skeptical.

Has anyone experienced this before? If I don't see any movement tomorrow morning, I'm thinking about filing a Missing Mail Search Request.

For anyone whom this might help, the package wasn't scanned in until it finally arrived at the buyers local post office. I shipped it Monday and no tracking was updated until today (Friday) on the day of delivery. To avoid this kind of problem in the future, it's best to stand in line and have them physically do the acceptance scan.

I always get it scanned and get a receipt, even if it takes a little while.

Without that acceptance scan, not much you can do if the package gets lost or doesn't get scanned somewhere down the line.
