Killer deal on 540mb MO disks

I just posted this in the 2000/XL forum. But I've seen a few people with rackmount samplers here that use MO disks and didn't wanna leave anyone out. There's a seller on ebay with Maxell 540mb MO disks (5 pack) for $30. These are hard to come by, and usually run for $20 or more each disk. So for $6 each, it's a steal.
