EDIT (in response to leddt since I can't reply): if you ask UPS to leave the packages without signing, will they refuse to do this even if they are placing it in a secure place?
(They are also starting to put up automatic stations, like the German postal service does.)
So when I order something, the default is that I get an SMS notification when I can pick it up at my local grocery store whenever I want, not that someone tries to deliver it to me while I'm not at home.
My post office is 5 minutes from my house. Open late.
Purolator/UPS, Fedex, and DHL are a bit more painful though. Close at 5, only open monday-friday.
Mail delivered on campus has been known to be delayed for > 4 days (sigh), and it's a great problem to solve.
TNT Post has "offices" located in many local stores so that's pretty easy.
They'll ship your items from Amazon to, effectively, Amazon, just closer to you.
I found a way around: get to know the UPS deliveryman, have him deliver my package's to the (neighbour's) back door when I'm not home. Mostly books, so nothing I would miss if it got taken.
I would love to see this getting major traction.
