Arthur Macarthy overpayment

Here's one that looks pretty legitimate. Except the email properties show it does not come from anyone called Arthur Macarthy.
Things to look out for are ones that don't mention at all where the property is and make a big deal about payment by whatever means.

Hello,

I want to make reservations for a two weeks period for the dates of 10th to 24th October,2007 preferably two double rooms that can accommodate two couples.Do confirm availability of accommodation for this period.

Please, get back to me with the full details, prices, total cost and discount inclusive of the available accommodation.Endeavor to get back to me as soon as possible and I do hope that you have a POS Credit card charging machine and that you accept payment with major credit cards?

Regards,

Arthur Macarthy
