Hi, I've pretty much decided to go with Johnstones Trade paint colour matched to F&B Stiffkey Blue for my bedroom. The question I have is is it best to go direct to a Johnstones Decorating Centre or can they do exactly the same thing at Brewers (which is closer to me and currently doing an NHS discount!)? Just want to know if there's any difference in machines etc that mean it's worth going direct to Johnstones for a better match?
