Vouchers that provide discounts are sent regularly to customers who have collected the required minimum points during the collection period and have chosen post as their preferred communication method. Vouchers and coupons also appear in the Clubcard account online and in the Clubcard mobile app. The minimum number of points required is currently 800. If the number of points collected from the beginning to the end of the collection period is below this minimum, the points will carry over to the next period. Points are credited in blocks of 100 for amounts over 800. Points below 100 are carried over to the next period. The collection period can vary, and Tesco reserves the right to change the minimum points requirement.
