In my relative's case, the following situations would not have occurred with a local pharmacy:
1) Delivery time from placing order unpredictably varies dramatically from 2 days to two weeks.2) USPS left order on doorstep (too big to fit in mailbox), was stolen, customer out big money and didn't get medication on time. Appeals and complaints to both mail order pharmacy and USPS have failed.
3) So the next time she specified "signature required" and paid extra shipping charge. Sent USPS regular again.
Fed. Up.
Sounds like something that Uncle Sam would be on top of eventually, but that would require the Fedzilla to care about what is reasonable.
Is it possible for her to get a bigger mail box or have it sent to a PO box, or someone who is always home, put up a sign asking the mailman to take anything too big for the mailbox back to the post office for pickup, etc.?
Get a mailbox that locks. I did after a little finagling with the local post master. And I live in the hills...
