After selecting your desired items and proceeding to checkout, you can apply a discount code on the checkout page before confirming your payment details. The field for the code may be labeled as Promotional Code, Discount Code, Student Discount, or Coupon Code, depending on the merchant. Once the code is entered, the discount will be applied to your total, allowing you to see the amount saved. Some offers may not require a code, such as exclusive discounts for brands like Samsung and Apple. Additionally, certain in-store offers may require you to present your Student ID for access.
