Wonderful! Use this service!
I love this feature! It allows me to put a specific amount on my account, which in turn controls my spending! I love Amazon's Kindle books so much. And a lot of the time I find many interesting books for under $4, and a lot of times for $.99! It gets easy to lose track of how much I'm spending, so having a set amount to spend and being able to check on it at will is awesome!
