In my 74 years(hit today) of life travels I have NEVER had any one cold contacting me be it via e-mail, snail mail, carrier pigeon, telephone, courier, swinging chick, telegraph, pony express, etc. with a "great deal" having my best interests at stake.
This includes TS share associated scammers, Nigerian Minister of Finance, rich widow of whoever in outer Mongolia or wherever, Mother Tresa's sister, lottery I did not enter, pyramid selling schemes, free siding , windows, alarm, etc, stock promoter, 20% interest in risk free investment, oil well, gold or uranium mine, vacuum cleaner or encyclopedia salesman, easy money flipping foreclosures(watch Discovery channel) , ad infinitum!

A fool and his money are soon parted!
