To take advantage of the S-zone promo codes, you typically needed to verify your student status through a third-party verification service like UNiDAYS or Student Beans.
These platforms are commonly used by various retailers to confirm a student eligibility for discounts. You would need to sign up for an account on one of these platforms and provide proof of your student status,
such as a valid student email address or other documentation from your educational institution.
These S-zone promo codes have been reported as expired or no longer working. However, it might be worth trying some of these codes, just in case you score a discount.
