I received an email which was virtually identical to the one in the article, including the misspelling of amount. What caught my eye was the use of a French ISP email suffix – that and some of the slightly odd phrasing in the email consistent with the author being a non-native English speaker, made me wonder if the perpetrators were French/French speakers, in which case it might be likely that they had gained my email address etc. by hacking a non-UK webshop (i.e. European, possibly French).
It would be interesting to know if other recipients of these emails have made purchases from any non-UK webshops.
