Steam recently started no-questions-asked refunds which is often better than a demo.

Been using it successfully. Just can't have more than 2 hours played.

Yeah, I know. I'd still rather have a demo. I don't like the idea of using my credit card as a means to demo a game I might be interested in. If a game I wanted doesn't meet my expectations after purchase, then that's a different matter.
