First, check the hotukdeals ProCook voucher code listings and home in on a deal that you want to redeem.
Copy or note down the code and click through to the ProCook online store.
Choose your items and when you're done, press the “view basket” button.
You should see your order total displayed along with other product information. Scroll down a little until you see a box marked “Apply a voucher code to this order.”
Simply paste or type in your ProCook promo code in the box provided and press “Apply”.
When that's done, your order total should be reduced according to your ProCook discount code straight away. You can then continue to check out as normal.
