I started to use this shop a few months ago and I can say that everything I have got from there has been cheaper than anywhere else - the exact same thing.
The people there are very helpful and will help you make decisions not based on the most expensive thing in the shop, but what fits your purpose.
You can also find everything on their web site and this saves you time.
