I used the website of a shop in Ipswich
www.actionoutdoors.co.uk and their service was very good. They did make a mistake with my order but they were excellent in sorting it - and this actually fills me with confidence as I know that if something ever did go wrong (as it can with any online store) then they will be on the case.
The biggest problem with shopping online is poor customer service and not knowing when your item might arrive etc.
