I've never had a package stolen from the USPS, but I *have* had one stolen from UPS. Back in 1974 I had some stereo equipment stolen in a break-in, and ordered a replacement to be sent UPS. The shipment arrived while I was at work, so they left a note that they'd try the next day. I called and said I'd pick it up from their office after I got off work. It was December, so there was a long line. After an interminable wait, they said they didn't have the package... must've gone out for delivery again by mistake. Got home, no note. Called again and repeated everything the next day. They finally admitted that they couldn't find the package, and blamed it on the seasonal help. They eventually paid for a replacement, after a lot of paperwork. In all the years since, though, I've never had a problem. (Of course, I became gun-shy about ordering "good stuff" in December!)

Fine if 'they' want to do this and pay for it. My complaint is buying goods from the US where I'm paying the P&P and not having the choice of a reasonably priced service. Why would I want to pay in some cases more than the value of the goods for postage, if I'm in no rush to receive them? -- *A conclusion is the place where you got tired of thinking * Dave Plowman dave@davenoise.co.uk London SW To e-mail, change noise into sound.

Dunno. It may have something to do with package tracking and fraudulent claims for loss or damage. The logistics companies give you one tracking number that works anywhere in the world, whereas the post offices all generate confusion and duplicated numbers that make it very hard to establish whether something got delivered, and if not, where it went. Here, there's lots of competition in logistics, so the service is generally excellent and the cost very reasonable. US postal rates are also quite low, which may make it more difficult for them to negotiate a revenue sharing agreement with higher cost organizations. (Canada Post is the example I'm most familiar with--at one point quite recently, all mail from the US to Canada had to go through the central Toronto sorting facility, even if it was a letter sent from Vancouver to Seattle.)

OK, perhaps I sh6ould have said *as* they-re energized (to keep th6e corollary with light bulbs burning out when turned on).

"Courier"? Do you mean "next day" services like FedEx and UPS? Yes, often time is money. "Couriers" are sometimes (rarely) used for intra'-city delivery when hours count. Intrest on a megabuck pays for courier service.

Sure, but not the tungsten, just the steel. The melting point difference is more than that between copper and solder, so it's more like brazing than normal welding.

Stew Leonard's Espresso Roast, roasted fresh daily in sunny Yonkers. Best beans I've ever come across, and worth the trip. Always a crowd pleaser.

Registered mail uses one tracking number worldwide too. It's R, a letter, a fixed length string of numbers and the country code. I can track a letter or package sent registered mail from almost any country on 17track.net, several other similar sites, and once it is here on the Israel postal site. The problem with the US is that they send regular international mail using a tracking number with an L at the begining, and those are tracked as far as the first post office the sender drops them off at. Occasionally they are tracked to a sorting center, but not always, and usually not. Several years ago the USPS restructured their rates for mail outside of the US. They dropped surface mail, replacing it with an air mail system that takes almost as long. I have had packages take 6 weeks to arrive here airmail from the US. They did a survey of prices of the courier services, and simply charge 1/2 of what the courier services do. If you want registered mail, they charge another $12 or so for it. Compare that to China which charges a few dollars to send a package, and another dollar or so for registered mail. Or the UK (and the rest of the EU) that charge about $5 for postage and registered mail.

No, they are rediculously high. Much more than an other postal service for international mail, they also have a very high theft rate, and will not insure their packages. As for rates, everyone pays the same rate by international treaty. So the eBay vendor in central China that pays a few dollars to send his package is paying the Israel post office the same amount to deliver my mail as the vendor from the US that pays $16 for the same size package. The profit/cost above it goes to their national post offices. It's like cellular roaming rates. I pay .73 NIS ($.20US) per minue to call on my cell phone from all over europe back to Israel, or to the US. Someone with a US company can easily pay $3 for the same call, BUT their cellular company paid the local company the same amount as mine did for taking the call and forwarding it over international long distance lines.

Sorry to hijack this thread but I have an actual electronics repair question: how do I go about getting my old AIWA CX-NA10 stereo system to read CD's again? Is the lazer bad?

Sounds like a bargain to me. Very few other organizations would leave money on the table like that. I sure wouldn't. Would you?

Plus they save on duty by claiming that everything is a gift. Such generous folks, those Chinese.

Dunno. I don't ship a lot of stuff overseas, so that's quite possible. However, they're terrific domestically.

What treaties are those, and do they guarantee the same rates for everyone?

Depends what's important to you, of course. Mostly when I'm in Europe I do my calling over wifi using UMA, so it costs the same as at home. But I only go there every couple of years.
