Not sure if these are nationwide, but I have received through the post, a whole leaflet of Domino's Pizza Vouchers
Various, including 50% if spending £30 or more
Not sure of expiry, if any, but there are 15 up for grabs. I shall include one of each per person at present.
Postage costs would be great unless someone wants then all. Maybe we could do a chain whereby I send to Person A, they take 2, send to Person B. etc. What why we only pay 40p postage.
