Any WooW points earned by customers within a calendar year (from January 1 to December 31) will expire at the end of the third year after the points were earned. For instance, if the customer earned 5,000 points on May 15, 2015, and 10,000 points on June 14, 2015, the customer’s total 15,000 points earned within the year 2015 will expire at the end of December 31, 2018
