Found 20th Feb 2017
Not sure if this counts as a Freebie or a Voucher because you have to buy Reveal magazine. You get a free Greggs bake (Katsu chicken or Bombay Potato only) AND soup (think it's from a choice of Tomato, Chilli or Vegetable). I haven't bought the magazine myself, so i'm only about 90% sure of the choices on offer. The offer is flashed on the top of the cover of the CURRENT issue of Reveal, which I think may only remain on sale TODAY, MONDAY 20th. So hurry up! I think the voucher itself is valid for about three weeks. Not much time left on this, hope it benefits someone!
