american lotto exchange compensation draw sweepstakes, LOTTOxCHANGE i was sent a letter from the LOTTOxCHANGE...SCAM SCAM SCAM 95588, California

i receieved a letter dated nov 5,2010 with a check and claim number.  I was told that i was approved for a lump sum of 440,000.00.  by a certified check that would be delievered to you by a courier company.  Also it said that i need to call the "claims agent" to let me know the process.  Then it  tells me that i need to claim my prize no later then the 20th of november.  The first thing i noticed that was suspicious was the envelope was from Canada, the letter was with a california address and the check was from a bank in buffalo, NY. RED FLAG #1...so i decided to go online and look on rip-off report .com and i found that someone else recieved the same letter with a less amount won but same amount check, same address of the company ..so i want to make sure someone doesnt fall for this scam so read EVERYTHING!!!
