Shopping for the Apple II user in your life? For less than $100, you can get a Uthernet  network card, a Focus IDE  interface card, every issue of Softdisk G-S  ever. Each of these is a significant and invaluable gift — but you may want to pick up something smaller and simpler from a mainstream retail outlet to stuff in a stocking.
For that need, I recommend floppy disk sticky notes .
This unique stationery is designed Burak Kanyak 
with attention to authentic detail. Whereas standard Post-it notes measure 3" square, these pads, like actual floppy disks, measure 3.625" tall and 3.5" wide, replicating the look and feel of when being able to hold 800K of data meant not needing three 5.25" disks. Each of the pack's three pads has fifty sheets, providing ample opportunity to leave 150 floppy notes and labels in your home, work, vehicle, or wherever a gentle reminder is needed, at an average cost of less than ten cents each (plus shipping).
For a retrocomputing enthusiast who still relies on this ancient medium, these notes are the perfect gift — as long as they don't end up accidentally inserted into a floppy drive!
