Mailboxes or post offices with late Saturday pickup times

[mermaidcafe.livejournal.com]

Hi!

I need to mail something postmarked by today. The Winter Hill P.O. and their mailbox outside had their last pickup at 1 and my own mailman came early this morning.

I know there's the all-night post office in Boston, but are there any closer mailboxes or post offices where I can still get something postmarked today?

Thanks!

Does the date on metered postage count as a postmark? I never see a post office cancellation on metered mail I get. And anyone can buy a postage meter.
