For example, a customer purchases the Base Wash at the regular price of $6. The customer will receive a $1 discount if they return within a 5 day period. To entice the customer to visit again within 5 days, a $2 discount will be offered. Finally, a $3 discount is offered to the customer if they want, they can return within a 5 day period. After the $3 discount wash is purchased the cycle starts again. See the following image for visual diagram.
