EBay is a cheap way. By the time the disc gets to you any possible covid virus on the disc will likely be dead if there is a greater danger from the postal workers who handled the outside of the package which is why I keep a can of Lysol inside where I bring my mail and I give it a cursory spraying and wait a couple of minutes.... of course I hate eBay management as well so there's always Craigslist but then you have to be careful when you visit somebody
