Big Scan supporter
I have to say that i have used Scan (based in Bolton) for several years now as my first port of call for all my IT components and have always found them to be excellent. On the few occasions that a part has failed, i have only had to pop in and swap it. Of course, I live only 20 mins drive time away, so this is far less inconvenient than a postal return, so that might highlight bigger issues.
I always find their website and online ordering system works fine - no problems so far. Plus, they have just undergone a major refurb, so that might account for some recent issues.
Overall, though, on price and service and quality, I would highly recommend Scan to anyone.
