The Celebration rule allows you to reward the customer on the new year celebration or any other celebration. This rule compels your customers to wait in your store for a particular celebration. The Celebration rule allows you to select a month and a day in the year to reward customers that have stayed with you for a long period of time as they get to receive reward points at that time of the year.
We recommend you set between 500 - 1000 as it is a once-in-a-year activity and it will increase sales as the customers will want to use their discount to make purchases.
