If Mom can’t use the Tattva Spa gift card by the expiration date, unfortunately, the validity period of 6 months is non-extendable. It’s crucial to utilize the gift card within the given timeframe to ensure its validity. However, in the event that Mom is unable to redeem it before the expiration date, there may be alternative options such as transferring the gift card to another family member or friend who can utilize it before it expires. While it’s disappointing that the gift card cannot be extended, it’s a reminder to plan ahead and make the most of thoughtful Mother’s Day gifts like spa vouchers within their designated validity period.
