The Loyalty Discount Program rewards customers for purchasing high volumes of products with increasing discounts, it is not a program that would reward fidelity of creators. Therefore, as a seller you have nothing to do besides validating your participation in the program in your account preferences. Your product will receive a discount within the range of a maximum of 30% of the price of your product or zero, it depends in the value of the incremental "coupon" the eventual costumer had got before purchasing your model/scene.
