* Business logic for calculating sales campaign prize
* • Every order that is placed is automatically entered into the draw
* • At the end of every day, two orders are selected from all those entered into the draw
* • Firstly, the order for the largest amount is selected
* • Secondly, the order for the smallest amount is selected
* • The customer who placed the largest order receives prize money equal to the amount of their order less the amount of the smallest order
* • The two selected orders are removed from the draw
* • All other orders remain eligible for draws on subsequent days
