I also get it direct from the suppliers. The price includes postage. Amazon sell it as well but it costs slightly more and still comes direct from the suppliers!

As Coco says, the 20kg bale works out a lot cheaper as it only costs £4 more but it's absolutely enormous lol. And it does need storing indoors really or it gets damp.
