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”.

Of course not, most coupons may be used only by you when you received them directly from Sglinkstore.com. As the Sglinkstore.com coupon includes your User ID, it cannot be resold or transferred in any way.

Simply, access the Sglinkstore.com site and find your coupons bar. All the latest

coupons will be shown out, note that the coupons bar will only appear when you have coupons available.

To avoid this problem, you should check out carefully Sglinkstore.com 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.

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