I live a few blocks farther from Magoun over in Winter Hill. I have the same issue with UPS, they refuse to leave any packages at my house if no one is home. That is pretty much all the time during week. I really don't know if UPS boxes would be stolen off the porch because they never leave anything, but USPS/Amazon Lasership stuff has never been a problem.

Really annoying and it makes online shopping so much less convenient.
