A couple of years ago Amazon UK somehow bamboozled me into buying a monthly subscription for a pot of hair product. When the next month's item was delivered and I saw the charge on my card, I was so infuriated that I impulsively disputed it. Months later, Amazon sent me a rude email asking for their money, but I eventually won the dispute. It feels kind of good knowing that I'm one pot of hair wax up on Jeff Bezos. (I did offer to send it back.)
