I used the AWS free plan many many years ago as a student. I was so paranoid about losing money that I immediately shut what I was using down after I thought I didn't need it any more (even though leaving it on was part of the free plan). I turned off the instance, but I forgot the public IP. A month later I got charted a few pennies because an associated public IP is part of the free plan, but an un-associated one isn't.
I didn't go bankrupt, but it proved to me how scummy AWS can be given that actually trying to use less is what got me charged.
