This has been posted before a few weeks ago but the price has just dropped by £20.
I ordered a grade A on Monday afternoon and it was delivered Tuesday morning. Apart from the packaging it looks brand new - even has the maker's protective film on! Apparently grade B's are usually really good condition also.
Not sure about current stock but you can sign up for email notification when what you want is available - that's what I did & only waited a couple of days.
