In case you enter a discount code during checkout that doesn't exist or isn't currently active, then you can see the message: “Unable to find a valid discount matching the code entered”.

To avoid this problem, you should check out carefully gooloo promo code before that promo code could be expired, some promo codes are tied to a minimum purchase, a first-time purchase, or tied to geography, and other reasons.

Once you find available coupon codes and are approved by the gooloo official store, you can submit them to us at Coupon Submission. We are not responsible for the reliability of coupons provided by customers.

The sitewide discount from gooloo is applied on certain purchases. For Year-End Deals, the store may have its own requirement to offer you a sitewide discount.

At the time of updating, gooloo has not applied Student Discount all year round yet. Check the official store and reach out to the customer support team to be clear.
