If you want to order and pay for a PC and then don't get it - go ahead and order from the HP Store.
When you try and phone aftersales (as there is no telephone number for them so phone sales and they put you through) you will receive excuse after excuse. They told me there was a internal fraud issue and then it was an issue with after care, then they didnt know why the computers were not dispatched as they were in stock. They told me to write in with a complaint - I'm guessing to get me of the phone as i never got a reply to my complaint either.
If you want your item delivered - order from somewhere else other HP.
