For $20 I will ship (yes this deal includes the shipping cost within the USA) 100 DS/DD 3.5" used floppy disks. Or for $10 you get the same deal but HD disks. Or for $15 you get 100 SS/SD disks. They have random Mac software on them, but the DS/DD disks should be perfectly fine for use on Apple II's using the old 800k drives.
I was asked about 5.25"floppies, I do have some for sale, but I don't know what the going rate is, so I'll investigate for I agree to any price.
If you are outside the USA, the shipping cost will be much more. I will ship to foreign buyers. The cost will be the same plus the actual shipping.
