array (   1 =>    array (     'name' => 'product 1',     'price' => '5.00',   ),   2 =>    array (     'name' => 'product 2',     'price' => '10.00',   ),   3 =>    array (     'name' => 'product 3',     'price' => '50.00',   ),   4 =>    array (     'name' => 'product 4',     'price' => '20.00',   ), )
