Am I right in thinking that if I purchase a Mac online from the Apple store, that I can return it within 7 days and have a full refund as per the Distance Selling Regulations - and I don't even have to give a reason? If so, what charges (if any) will I face? Restocking fee? Postage? And am I still entitled to a full refund if I've unpacked it and "inspected the goods" as it were? (ie. switched it on, checked the screen, ran a few apps)?
