I had to check your profile to see if you live in my town. Must be more than one of them.
I had a carrier roll up a college book to fit in the box. it broke the spine or a $100 book. I called the lady postmaster to complain and the 1st words out of her mouth were "I am so sorry" (oops wrong company) she really said "did you have it insured?" she would not foreward my call to the main postmaster.
Now on the other hand I have a company P.O. box in another town because I can't stand my local PO.
The other day my postage came to around $26 and their machine would not accept my credit card. Then the other two tellers said they had the same problem. The system was down. My packages were stamped and tossed in the bin, but I couldn't pay. (no cash or checks on me) So what did the teller say? Just give me an IOU. I thought he was kidding, no he scribbled something on a piece of paper and I signed it. I brought him the cash later that day. We are all on first names at that PO. It is a very small town PO. So small my GPS can not even find it.
Must have been nationwide, a few days ago they had signs up "system down". Though what really surprises me is you don't use ebay labels?!?
