You can also check the statistics to see the orders you receive commission on in real time. is what we would say so it needs to give them a special code current statistics on that code like how many people used it and how much money or store credit made also would like to be able to change the percentage at any time the code will be used at check out when the order is complete then it counts i want it clean and easy to navigate the person i choose will need to show a portfolio of work they will be doing on going updates for income they will be promoted throughout my networks
