So I've ordered 4-5 things this holiday season from the Apple Online Store.. 4/5 of the items said they would require a signature when delivered and they were left at my front door without a signature required. Just wondering if this is typical or what's going on? Why are they saying that I'll have to sign when I don't? Even the tracking #s they release to me doesn't say signature required. I guess it's no big deal, but just kind of weird as it's been happening a lot.
