Expected value payment method and system for reducing the expected per unit costs of paying and/or receiving a given amount of a commodity

A method of betting between a first party, called the Buyer, and a second party, called the Seller, for reducing the expected per unit cost of paying and/or receiving a given amount of a commodity comprising the steps of:

• providing a commodity, said commodity representing a plurality of units, defining an amount of a commodity as a specific number of units of said commodity;
• providing money, said money representing a plurality of units of currency, defining an amount of money as a specific number of units of said currency;
• providing a random number generating device comprising a means for selecting a given amount of money and a means for randomly generating an integer from a set of consecutive integers, the total number of consecutive integers from which said integer is randomly selected being equal to the total number of units of currency represented in said selected amount of money;
• wherein said set of consecutive integers comprises integers starting at the smallest integer "1" and ending with the largest integer equal to the total number of units of currency represented in said selected amount of money;
• defining a per unit cost of an amount of commodity as the amount of money to be paid for said amount of said commodity divided by the number of units in said amount of said commodity;
• said Buyer intending to buy an amount of a commodity from said Seller and said Buyer only willing to spend a first amount of money for said commodity;
• said Seller providing a first offer wherein said Buyer would pay said first amount of money to said Seller, and said Seller would then pay said Buyer a first amount of said commodity at a first per unit cost;
• said Seller providing a second offer wherein said Buyer would pay a second amount of money which is greater than the first amount of money to said Seller, and said Seller would then pay said Buyer a second amount of said commodity which is greater than the first amount at a second per unit cost which is less than said first per unit cost;
• said Buyer wishing to buy an amount of said commodity at said second per unit cost and willing to only spend said first amount of money, entering into a bet with said Seller, said Buyer paying said Seller said first amount of money;
• operating said random number generating device by first selecting said second amount of money on the device, then operating said means for randomly generating an integer, wherein the odds of the random number generating device selecting a winning integer favorable to the Buyer is equal to the first amount of money divided by the second amount of money;
• said Seller paying said second amount of said commodity to said Buyer if the randomly selected integer is a winning integer;
• said Seller paying nothing to said Buyer if the randomly generated integer is a losing integer."
