Lost some files in AWS Glacier? I found ’em

During my last few visits to the AWS Popup loft, I really dug into my Amazon Web Services account, especially the billing. My bill had skyrocketed to over $5 a month! What had happened? How did I miss this huge spike in billing? Well, it turns out that a majority of that bill was from AWS Glacier, I must have stuck something in there for safekeeping and forgotten about it.
