CSP's numbers are still a bit raised but I don't know if it will work for those purposes. Now that you bring up raised numbers, I remember back in 2008 or so a store's CC machine was not working one morning and I bought $200 worth of product. I never saw the charge show up for months and months. 3 months, 6 months... people told me to cancel the card already. Still nothing. Ten and a half months later... bam. I almost forgot about that charge!
