You will continue to have access to the existing WXT Rewards programme for 1 month from the date of the launch of the Paid Subscription programme (‘Grace Period’). The Grace Period will cease to apply after this period.
Suppose you decide to upgrade the Free Subscription to a Paid Subscription during the Grace Period. In that case, all of the benefits attaching to the existing WXT Rewards programme available during that Grace Period will be cancelled, and after that, replaced by the discounts available via their selected Paid Subscription. Otherwise, you can make use of the benefits attaching to the existing WXT Rewards programme for the duration of the Grace Period if you remain on the Free Subscription during that period.
