Yep, doing budgeting at the end of the month and I found a $20 Amazon charge. Turns out it was from a little bit of data I left on their DB service (which took _a lot_ of clicking to find the one I was actually using) after my free year had expired. Certainly not thousands of dollars, but for just experimenting with the system months ago, it was a rude wakeup call. Ideally I would have been able to say "Never spend more than $0.00, kill any services you have to, I'm _only_ using this for evaluation."
