Speed doesn't usually come free, but you get what you pay for by chipping in a bit extra to get your gifts under the tree on time. Amazon bases its whole Amazon Prime ecosystem of video streaming, book lending and express shipping around this idea. For $79 a year (or, soon, $8 a month), Amazon will ship any item in two days while offering access to streaming movies and video and titles from the Kindle Library service.
Retailers can offer you prices and promises, but what they often can't do is truck over your item themselves. Some sites try this approach with third-party companies such as Amazon partner Lasership -- basically somebody in a car who takes your package from the nearest fulfillment center and drops it off at your door -- but usually you're going to have to go through a shipping company. Unless you're a strong DHL adherent, that means using UPS (UPS - Get Report), FedEx (FDX - Get Report) or the U.S. Postal Service. So which one keeps your holiday gifts safest? Popular Mechanics set out to answer this question two years ago when it took packages, stuffed them with a three-axis accelerometer, thermometer and a data logger to measure movement, g-force, temperature, orientation and other factors. If the packages they shipped were flipped, jostled, flung, overheated or frozen, they were going to know about it. So what did they find? A mixed bag. If your item is going to be particularly sensitive to flipping, don't give it to the postal service, which flipped packages 12.5 times during a three-day trip. FedEx was somewhat better with seven flips per trip, but UPS only needed to move packages an average of four times during their journey. That's an extremely soft touch given the competition. Unfortunately, UPS has no problem chucking your item around like a rugby ball when it departs and arrives. The packages registered an average of two acceleration spikes of 6 g's or greater per trip. That's the equivalent of dropping it 2.5 feet each time it's loaded on and each time it comes off the truck. FedEx is similarly rough, tossing packages 3.1 times per trip. The USPS shows a bit more restraint by keeping the drops to 0.5 for each package. Meanwhile, if your present can't take huge swings in temperature, FedEx is your best bet. They kept the average temperature swing for packages at 26.1 degrees, while climates in UPS trucks and facilities varied by 29.8 degrees and USPS went through hot and cold flashes that varied by 32 degrees. All three shipping companies had one very important feature in common, though: If they got packages labeled "Fragile" or "This Side Up," they flipped and flung them all the more. You're better off affixing a sticker that reads "Use me as a warehouse soccer ball." -- Written by Jason Notte in Portland, Ore. >To contact the writer of this article, click here: Jason Notte. >To follow the writer on Twitter, go to http://twitter.com/notteham. >To submit a news tip, send an email to: email@example.com.
