For those moving near Okehampton you must check out Trago Mills, near Newton Abbot. A short trek out but I guarantee it will be worth it. I used to live just the other side of the roundabout from it before moving to Cheshire a few years ago, and I used it all the time. Really good for workshop kit outs and the like, plus fitting out a new house. The whole family will like it (it has an amusement park, petting zoo etc.), bargains galore, lots of great kit and probably the best prices you will find anywhere. They sell all of the construction equipment and a lot of softwood, sheet material, plumbing, electrical, the whole lot really. When I left they were about to open a brand new purpose built DIY & Tools building. Oh, and they have one of the best and cheapest garden cetres around the area as well. Probably the main thing we miss about moving away TBH!
