Is this an issue or not? I thought they were for documents only according to ppl on here/usps. The last time I got something bulky in a priority envelope, it was delayed & had to be checked by a postal inspector. This time around it got here fast...2 days...
So does usps just not care about bulky envelopes?
It's gotta be able to fit through the mail sorter without issue, or else it's gotta be hand sorted.
