Like Lisa below, I was charged over $5000 for a $39.99 USD product, ironically at about the same time the review appeared. Luckily, it was never processed by my bank as it was immediately flagged but they told me I have to change my credit card due to its extremely unusual nature.From the exact charge, it looks like they are converting USD to whatever currency your country is using, and then moving the decimal over two places. For example, 39.99 USD to CAD would be ~ $5495 CAD. However, there's also some extra in there, so it would be $5495.77 or something. If this is a math error in their system it's extremely nasty and should never have passed any sort of testing.Not that any of that explanation helps as I await a new credit card and look forward to dealing with all that entails.In order to even submit a ticket with teachable I would have to create an account there, Because I never did get what I was hoping to and the charge never went through there was no point as I am now very unlikely to ever use their site.------Edit for clarity:When placing the order I received an alert from the bank about a suspicious $5K+ charge and was asked to authorize it. As I had obviously not placed such an order the bank cancelled the transaction before it was ever processed. As a result this charge did not go through, but I was still told that I had to replace my credit card.Because the transaction did not go through (hence the title of "Attempted $5000+ charge"), I did not create a teachable account nor did I wish to do so to report the error; you should be able to report these things without creating an account.
