I had the same trouble with some medications needing my signature. I am usually here but didn't like that. Now they go into my mailbox down the street.
but now the mail person is putting someone else's mail in my box (the street the box is on!!) and i don't live on that street. whom ever it is just uses the wrong side of the box!! i delivered that days' mail myself!
OH I will say i now just get meds at the pharmacy rather than use my extremely expensive insurance pharmacy mail order people. hated them. I get it cheaper now too.
