Hi, first deal.
I just ordered a refurbished laptop at Dixons, added to cart, went to check out, choose the next day £3.99 delivery, then it gave a discount of the below
Order subtotal £349.99
(Including VAT) £301.48
I am not sure whether this is just rerurbs, but I did add another refurbished laptop, and it added the discount again.
Note that works with standard delivery as well (you still get discount and is free delivery).
