I purchased some stuff from Amazon a couple weeks ago. Got a tracking number and all. And then the package (shipped via US Postal Service) got to the neighboring town, went "out for delivery," and never made it to my house. It's been a week. Local post office surmises it'll get lost between post offices and may take weeks to find its way to me. Thanks to all the Cliff Klavens out there.
So I emailed Amazon (who can obviously track the package, too, and know I'm not making this stuff up) and within 24 hours they sent out a replacement package, overnighted by Federal Express. Got here today, as promised.
Amazon service--it's like the Pelican Parts of books.
