As for the missing refunds, I have called B&N regarding this and after 15 mins on the phone to someone who sounded like she was on MSN to whoever was able to ask questions (thankfully I used Skype) and said 'One Moment Please' 19 times I was told that it had been done and I should check with Paypal.
I called Paypal and after getting through the automated system got a very helpful guy on the phone who was able to give me a 100% guarantee that B&N had not refunded anything but the shipping and hadn't made any more transactions on my account.
I then called B&N AGAIN and after another 15 mins with a different person (being able to tell them that Paypal said there was nothing pending, going through the system, etc was invaluable) it has been 'escalated' I have been promised an email or phone call within 24 hours.
I didn't even want the money back, if they had been in any way useful I was going to get them to send my nook to a friend in CA to bring over to me in a couple of weeks...
Do I still want the bloody thing?
