Sir, I would like to purchase your beautiful timepiece however I am located in Nigeria. If you approve, I will pay you via a cashier's check in the amount of $1M. The check is drafted using funds from an offshore account and I cannot change the face value of the check. Once you receive the funds, please send the watch and a cashier's check for $300,000. You may keep the remaining $101,000 for your troubles.
Thank you sir.
