Malazan Empire: This book(trade paperback) is worth a lot of money! - Malazan Empire

I've been searching for the trade paperback of GotM for well over a year now and this week I had the opportunity to buy one on Ebay. The auction started on 3,5£ and 20 minutes before the end of the auction yesterday the price had gone up to 25£. Still a fair price for such a rare book. I bid 26£ and reloaded the page every 30 seconds to see if the bids would go up. Then 2 other bidders drove the price up to 41£ 2 minutes before the closing of the auction. I wasn't willing to 42£ plus p&p for this book. Over 40£ is a disturbingly high price for a book released only 4 years ago at what? Not even half that price? I'll continue my search for a trade paperback of this book, but I fear it'll never be a bargain if I find one again.
