Thornton's Chocolate website have a promotion on for free chocolate and you ony pay the delivery!!
Put in an order of up to £20 and in the promotional code type SN18, (or SN16 if that doesn't work!) and you will then get your order free and only have to pay the delivery cost of £3.50 remember to tick the box saying standard delivery when it asks as you're paying (not Gold delivery)!
I actually went over the £20 by a couple of pence and only have to pay the difference on top!
I think you can do this as many times as you wish but each order can only max £20 for the £3.50 delivery offer to take effect! But don't get greedy, you might get belly ache!
Perfect for Morther's Day or just to treat yourself!
