You need to be signed into your JD Williams account first. Once you log in and view your trolley summary, the 'Got a promotional code?' field should appear right there before you proceed to payment. Type it in and click apply to update the total.

If you don't mind picking up the parcel yourself, you can get free Click & Collect to an Evri ParcelShop when your order reaches the minimum threshold, which is typically around £30 to £40. That saves you having to pay the standard delivery fee.

For frequent orders, look into JDW Unlimited. It is an annual delivery pass costing £15.99 that gives you unlimited next-day delivery and returns for twelve months, so it pays for itself fairly quickly if you shop there often.

Look out for app promotions as well. JD Williams occasionally runs vouchers specifically for their mobile app that bundle a percentage discount together with free standard or next-day delivery.
