I really have no idea. But I can't remember ever seeing a bulb fail after being on for a while. (I'm sure it must happen.) It does, I have seen it quite often. :They almost always go when you turn them on, from which I conclude that the turn on is more 'stressful'. Indeed, this is usually when filament bulbd fail. : Say does Don Klipstein still lurk here? He may have some info on turn- on failure. http://donklipstein.com/ George H.

If it is a gift and the price is low, then they can pass it without inspection, and if it is inspected just look for the diamonds, guns, drugs, etc hidden in it. For example, just ordered about several each of 10 different items (around 40 items in all), from a vendor in Hong Kong. If he sent it to a US address and lists it as a gift, the US customs can do a quick inspection if they do any at all. If he declares each item, and they inspect the package, they have to figure out which is which, measure and weigh them and ascertain that they are what is claimed, and the weight matches.

If you were a logistics company, or for that matter a unionized proletarian, you charge what the traffic will bear. That works as long as there's competition--the more the better in general. You can't keep jacking up the price if your customers can just go down the street to your competitor.> > If you want everyone to have a small business selling items over the internet > then you keep your postal prices low.If you want to have economic efficiency, you avoid state enterprises and subsidies except where there's a compelling interest at stake--for instance the French pay more for food because they in effect subsidize small farmers, in order to keep the life of rural France alive. I'm quite fond of rural France, so I can understand their point. Postal services? Well, sure, folks in the boonies need to be able to send in their tax returns. ;)> >> Plus they save on duty by claiming that everything is a gift.

Some places think free wifi is a right, others > charge you high rates for it.Generally the places I've stayed have had free or at least cheap wifi. That's in Flanders, Artois, and Florence, most recently. And anyway, since I'm on vacation when I go there, I don't really want to be in constant touch with home!

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?Have you ever tried to mail a thousand+ packages a week? A local non profit group had a post office refuse their business, because of the volume. they had to get a politician involved, since USPS is the only way they are allowed to ship the gifts to our troops. Over $100,000 a year in postal fees, and were told to go away. By law, they can't ship a box full of stuff to a base. Each package requires a separate customs form to be filled out by hand. UPS and other shippers park an empty semi trailer at the dock of large customers, and haul it directly to the hub. That entire process can be automated.
