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 trilab. As the trilab coupon includes your User ID, it cannot be resold or transferred in any way.

To avoid this problem, you should check out carefully trilab 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.

Shoppers can get coupons for their first purchase at the store. However, it is not all the time, sometimes, they cannot apply a discount on items selling out or items not contained in the promotion program. It depends on the time you shop at trilab.

Let us know via email, our team will confirm with trilab to fix and remove all Promo Codes, Coupon Codes, and Deals that aren't working.

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