That's the Post Office - Royal Mail & Post Office Counters are different businesses, Royal Mail is the letters delivery business whereas the Post Office have the High St shops with all these fancy add-ons as well as the traditional books of stamps. I'm guessing if they are sold off then the sub £1 monopoly will go allowing other couriers to deliver letters making the market even more confusing.
Ah yes!!
Oh well, took a punt via HL for 2.5k. Seems we should get at least the guaranteed £750 and according to he Telegraph, if the city expectations are right that should see an instant £250 profit!
