USPS, Fedex, UPS will all pick up packages if you prearrange a pick-up time. I wonder if that's what she meant.
Other than that, as far as I know, your regular carrier will pick up mail for you, if you leave it in the mailbox in front of your house (Or wherever you pick up your mail.)
Yup. Just re-read your post. Sounds like we're talking about the same thing. I usually take my mail to the post office or to a large mailbox/dropoff location. But, if I wanted to, yes, I could leave my mail and the carrier would pick it up, free of charge.
Yes. Convenience is everything. :wink:
