Thorntons promo codes

We list 17 Thorntons codes, but none has passed a checkout test yet. Treat them as unconfirmed and try the first one listed.

The strongest offer we have on file is “20% Off Your Order”. It has not been verified, so it may not apply to every basket.

1 of the listed codes is described as sitewide. The rest are limited to selected items, a minimum spend or new customers; each code lists its terms where they are known.

Select “Show code” on this page and copy the code, add your items to the bag at Thorntons, and paste the code into the promo or discount field at checkout before you pay. The order total should update straight away; if it does not, the code does not apply to your basket.

The usual reasons are an expired code, sale items that are excluded, a minimum spend that has not been reached, or a code limited to first orders. Codes marked “Verified” were accepted at checkout on the date shown; unverified codes are listed as found and may already have ended.
