Confirming my earlier opinion...

It appears that the price of 3" floppy disks is indeed somewhat silly. As in someone from the USA bought the nine I had for £22, with nearly £21 postage and US sales tax on top of that!

I'm beginning to think I should forget about selling cameras and lenses and just concentrate on the weird stuff that sometimes turns up...

Weird... blank 3.5's on Amazon are about $1.25 each in the USA from what I can see on a quick scan...

No, these are 3" floppies, as used by Amstrad word processors and a handful of home computers, not 3.5"

According to Wikipedia "The disk format itself had no more capacity than the more popular (and cheaper) 5+1⁄4-inch floppies. Each side of a double-density disk held 180 KB for a total of 360 KB per disk, and 720 KB for quad-density disks.[38] Unlike 5+1⁄4-inch or 3+1⁄2-inch disks, the 3-inch disks were designed to be reversible and sported two independent write-protect switches. It was also more reliable thanks to its hard casing.

3-inch drives were also used on a number of exotic and obscure CP/M systems such as the Tatung Einstein and occasionally on MSX systems in some regions. Other computers to have used this format are the more unknown Gavilan Mobile Computer and Matsushita's National Mybrain 3000. The Yamaha MDR-1 also used 3-inch drives."

I suspect the buyer wants them for the Yamaha thing, which is a recorder for one of their synthesizers.

Thank you for clarifying, these are not a format I had encountered (I know of the 8" floppies, and the later 5.25" and 3.5" and worked with each over the years).

These were not 3.5" floppies - it was an odd format used for Amstrad's proprietry not-a-pc machines before the x86 clones monopolised the market.
