I've had a few issues with Amazon UK recently, mainly with delivery. I had a spate of orders that weren't delivered by my chosen method (first class mail, so that I can collect easily), when challenged, they saaid the item was too large for first class mail, but couldn't satisfactorily explain why I was given the option. Then I ordered the 24mm f/1.4 MkII, but it was returned, due to non-delivery. When I asked them why, their answer was "we can't determine the reason as we are an internet company" and they invited me to re-order. To say I was less than impressed and declined their offer was putting it mildly. The last problem was through their marketplace, so not really their problem, but I ended up getting completely the wrong item and in fact, the despatch note had someone elses details, yet I've been told that they have to inspect the item first (upon return), before they can issue the correct itme, despite receiving a photograph of the incorrect item. I am now very selective in what I purchase from them and they are usually the last choice.
