Useless
In the past six months I have tried and failed to give PC World some money:
1. Tried to get the RAM in a MacMini I had bought from them upgraded only to be told they don't support them yet on the website they claim they will work on an PC.
2. Tried to buy a white iMac after the news ones had been released (I don't like shiny screens), they had a good discount which tempted me. They dicked me about for a week before I gave up and ordered a refurb from Apple.
3. Tried a buy an external drive, used the Collect@Store. When I got to the store I got some feeble crap about they couldn't located them ATM but yes they had six in stock, but would you like this Maxtor instead. I told them to fuck off.
I've now given up on them completely, should have done years ago but sometimes it's more convenient to just go to a store than order online.
