Once you’re done with your online shopping, simply head to the checkout to put in your code.
It varies between different retailers, but normally there will be a box titled ‘Promo Code’, 'Discount Code' or ‘Student Discount’ on the checkout page, just before you put in and confirm your payment details. Once you’ve put in your code, the offer amount will be taken off the total price so you can see how much money you’re saving.
There’s no need to thank us.
