These methods ensure that you're never paying if you're not getting value (or that you can immediately stop paying should you stop getting value), and in my book, that's a perfectly reasonable method of charging for any service.The analogy I like to use is, "Would you consider it reasonable for a restaurant to charge upfront for 10 meals before you've had an opportunity to try the food."
