Are you anywhere near Denver?
We use the USPS to deliver books ordered on riflesandrecipes.com, because in our dinky little down it's far easier than Fedex or UPS. But once in a very great while an order gets caught in what we've come to call "the Denver Vortex": It gets there, then stays there for up to a month, apparently whirling around inside until one day it gets spit back into the delivery stream.
