GoDaddy's Economy plan is presented as though you can't sign up for a month-to-month payment plan (the lowest price displayed is for a three-month minimum sign up period), but once you add the plan to the cart, the one-month plan appears.

We couldn't find it until a GoDaddy pointed it out after we complained that the option didn't exist in a previous version of this review.
You can also purchase Secure Sockets Layer certificates (starting at $69.99 per year), the software that's represented by a green padlock in your web browser when you visit, say, a financial institution's website.
