All looks good and you pay the money to whoever. A few weeks pass by and your bank discovers that the Nigerian, or whatever, cheque/money order is a dud and THEN refunds themselves from your account. Bingo, you've been done.
Recentle however, the law has changed and the bank has to honour the transaction whether they're out of pocket or not. Can't remember what the new time limit is but it's now days rather than months.
If the scam's in your favour, go for it. But make sure that the above is 100% first
