OK, I just bought and picked up 50 of these (5x10-pack) to see what I would get.
They are all Made in Singapore. I repeat, they are all MIS.
They are all individually wrapped in thick jewel cases.
The reason that shipping costs so much is because of the thick jewel cases, and the fact that every ten of those comes in a cardboard box, and then, five of those fit inside another cardboard shipping box. So, 50 of these disks takes up the volume of six or seven regular 50-piece cakeboxes (300-350 disks). The shipping cost is obviously not them trying to gouge you, but merely something they can’t avoid.
BTW, these disks are mint, still in the original shipping box when they were sent from Verbatim to Plextor (Unity Electronics is Plextor’s authorized repair/wholesale/refurb/etc. place, so anything that Plextor is clearing out goes there first). The date on the 10-pack boxes and the shipping box is November 12, 2002.
