Tafetta cloth?

There's a very limited supply of people who would pay 3 million for that. If they were worth 3 million then those cheap ones would have sold quickly and people would be forced to buy the more expensive ones listed. Supply and demand.

The ones listed in the millions sold very fast, so there was really no reason to undercut down to ~200k in a couple days. They would have kept selling, if people didn't feel the need to undercut by 500k+ at a time.

For what it's worth, next time you can just say "I don't understand economics" and we can all move on.
