BEWARE:  There is no free lunch.  You will not just win a lottery that you have not entered.  This one works like this.  You receive a letter stating that you won a lottery and there is a check for $X in your envelope.  They state that after you deposit the money, write them a check for $Y and send it to them for processing or some other reason.  You check out the bank and it is real.  You contact the bank and ask if the check for $X will clear and they say yes.  So all is good?  NO.  Apparently the account number and the "bar code" do not match.  The bank WILL put the money into your account but much later, after you write the check to the scammer, they will take it back indicating that the code and account number did not match.  You are out the money!  A version of this scam has even taken attorneys for a lot of money.  Be careful.
