Just had to pop into Wickes to pick up some tap washers, whilst there had a wander round and came across their test pots of Vinyl Emulsion, which appear to be on offer at present. All Wickes 75ml test pots of Vinyl emulsion were just 50p each. Seemed ideal for painting up bases and small size pieces of terrain, especially considering the vast range of snad, dust and off white colours available in the range. Their sharp sand is also a pretty good price, though you'll need the car to carry the bag back(unless when you are not wargaming you are working out in the gym).
