A discount code works by giving you a reduced price or other benefits on a purchase when the code is applied during the checkout process. Here's a step-by-step explanation of how to find the right discount codes and how they work: 1) Obtain the discount code: You first need to acquire working voucher codes, which can be found on the retailer's website, through marketing emails, on social media, or via third-party voucher websites like VoucherAlarm.com. 2) Shop for products or services: Browse your favourite online shop and select the items you want, adding them to your shopping basket. 3) Apply the promo code: During the checkout process, there will typically be a designated field, box, or option to enter a discount code. You enter the code in the provided space and click an 'apply' or 'submit' button to confirm. 4) Verify the discount: Once the code is applied, you should see the discount or promotion reflected in your order summary. 5) Complete the purchase: After verifying that the discount has been applied correctly, you proceed to finalise your purchase by entering your payment and shipping information.
