One brochure gives you the option of buying a "full ticket" for $766.90 or a "half ticket" for $391.90.  After paying, you receive a "confirmation package" containing a listing of the numbers on your tickets and a letter informing you:

"You may WIN and receive a certified check for up to $10,000,000 U.S. CASH! 

One Lump Sum! Tax free! Your odds of winning are only 1-6! 

That is FANTASTIC! GREAT! THE BEST!"

The confirmation package contains a "Customer Service" 800 number so you can contact them with questions about credit card billing. It also contains a credit card "authorization" slip for you to sign and return, even though they have already charged your credit card for the purchase. 

This authorization will be used to persuade dissatisfied consumers not to seek a charge-back from their credit card company.
