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 if they purchase that same $6 Base Wash. To entice the customer to visit again within 5 days, a $2 discount will be offered off of the same Base Wash at $6. Finally, a $3 discount is offered to the customer if the return for the same $6 Base Wash, and can return within a 5 day period. After the $3 discount wash is purchased the cycle starts again.
