This is a great show at a great price for the 3-season set. I ordered it two days ago when amibees listed it as £12.99 at Play.com. It was £17.99 at Amazon at that time; because I had searched for it recently, it popped up on my main page when I went back to Amazon, now at a price undercutting Play by 1p!
Play.com said it was out of stock when I ordered, it now says "packing." I really hope that means they actually got more stock and will be sending soon, because otherwise I'd grab up this deal at Amazon!
