I ordered something a couple days ago to an PO Box and informed delivery told me it was going to arrive Saturday, but it was delivered yesterday with no notification from informed delivery. I had stopped by yesterday afternoon to pick up mail and didn’t see the package. The only reason I know it was delivered was because I had checked my informed delivery today where it says it was delivered and available for pickup early yesterday morning. This has never happened before and usually the post office workers are very diligent about putting packages out. I am now hesitant to go to my PO Box and am considering just canceling it. Has this happened to anyone else? Am I being paranoid or doing the right thing by not picking it up? Thanks.
