Instructions:Just had this email through from Additions Direct:
"To welcome you back we'd like to offer you £30 off your next order over £60
With NEXT DAY DELIVERY and FREE and easy returns we think you'll agree, nobody offers better value than Additions Direct.
Just place an order for £60 or more and quote code ZQ499*. You only have until 11pm on Friday 15th May to take advantage of this offer. This offer is not available online, call 0844 822 0099 to place your order."
Looks like it should be available for any customer, not just new!
