SCO would rather you volunteer to buy their license online, so they dont have to risk going after you by mail or using threats, maybe... those pesky laws being how they are. Or maybe they hope to escape the bonds of the GPL this way. Or just maybe they are about to sue some folks, and theyll make them an offer they cant refuse: pay for a license instead of a lawsuit -- its cheaper. It might have worked at one time, but after all the indemnification floating around, I cant see it.
But its up to you, gang. If you want em, you can have em. Licenses! Fresh licenses for sale! They accept credit cards. Do check the EULA, though. No indemnification. Eeek. Oh, and you have to agree to their expansive definition of what their code is made up of. And then there is that little matter of your firstborn.
Heres my version of their EULA. As you can see, they are obviously just horsing around. They start out pretending to be serious, but by the middle, its slapstick comedy. Ive rendered their jokes in red text, as well as points to note, like a red flag. My reaction is in blue. Then Ive put the GPL, taken from their website, just for comparison, at the end.
