I'm having trouble entering a student discount codeUpdated a year ago

Once you’re done with your shopping, simply head to the checkout to put in your code. On the right hand side (desktop) or under the ‘Show order summary’ drop down menu (mobile), you will see a box that says ‘Gift card or discount code’. Input your discount code here and click ‘Apply’. 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. Then confirm your payment and delivery details, and checkout as normal.
