this issue could be part of the bigger postal problem (its going broke!). It seems there are rules and regs, but each PO only follows them as "suggestions". So how is the public supposed to know who does what?
I can use 2 PO in my area. One is very uptight about things (but, then again, it depends who works the desk that day). The other one lets anything go. Across the street from one is a UPS dropbox, and I can phone/email for UPS/FEDEX service, which can be cheaper/faster sometimes. I usu use UPS to ship things. sharet
