The Global Shipping Program is a @($&@^ joke. They will actually unpack items that the seller has packed and put them in smaller boxes with less packing to save a few nickels, which of course are not passed on to the buyer. I had an item damaged in this way years ago and found out this was what happened.
Their latest scam is apparently limiting the shipping options when a listing is created to UPS or FEDEX or both. When asked why the post office does not appear the folks in the Philippines have no idea.We can be sure no money is changing hands though.
One has to recognize that these companies are permanently afflicted with eager apple polishers all looking to reinvent the wheel and so get a seat nearer the front of the class. And new generations of apple polishers are constantly recruited who know next to nothing about eBay, what works or doesn't. All they know is they need to DO SOMETHING NOW to justify their existence. Frequently the bureaucratic imperative of making sure you're never without something to do also comes into play, and the operative principle in that game is make sure you never completely finish anything in a way that won't need to be tweaked, revised, etc. And of course all driven as usual by the obsession with short-term profits to maintain share prices to keep the investment funds happy.
