I think you find out most about a company when they are operating in "failure mode". CPC just did this, and they passed with flying colours. I'd ordered some bits and bobs for the wedding lights (where I've been spending most of my time recently - big reveal to come later - at a wedding) and I'd ordered a pack of 10 plugs. However, just 1 turned up in a bag all on its own.
I rang up CPC and told them how lonely the plug was, and how it was missing its 9 friends who somehow seemed to have got left behind. They promised to sort it out and the following day a box with the missing plugs in it turned up. Of course I'd have been slightly more impressed if it had all arrived at the same time, but I'm very pleased to see that when things don't go right they own the problem and then fix it.
If you are buying any bits and bobs they are a great place to take a look. Their service is good (see above) and their prices are pretty reasonable too.
