[cctalk] 8" floppy diskette storage cases

Does anyone have, or know of a reasonably priced supplier of good clean used, or new 8" floppy diskette boxes? The kind made of plastic like these? https://www.ebay.com/itm/134258177087 I have one 8" box with Xerox software in which the plastic literally crumbling. The price this seller wants for the case itself is reasonable but I find the price of shipping outrageous. Total shipping price for three boxes is shown to be $21.35. I may be crazy, but this seems nuts for something so light. Thank You Don Resor
