Djtux,
I understand that you have your costs and I think it is fairly fair you charge for your service, that I have already appointed as very useful. My other concern beyond safety is how to interrupt payments when using stripe? Automatic payment with CC are usually a pain in the neck when you decide to stop it. I like the control over my payments that PayPal gives to me, allowing just discontinuing an automatic charge.
