Yeah - if I'm asked for payment info during a demo period, I'll probably just move on and find something else. For one, my wallet generally isn't near my computer - but even if it is, I don't like giving out my CC number for something I may use once and then uninstall (because I might forget to cancel the payment plan). As a startup, one of the things you're selling is great service. So get some contact info and contact them with a few days left and ask if they'd like to re-up.
