You are buying a muntie that has been shot and gralloched, you have not had to do anything yet, its up to you if you dont think it is worth it decline gracefully, they guy might have paid to go stalk it ( posibily £80 a stalk), so he sets his price,,, i doubt if he is making a profit, probably just trying to get some of his money back
but it is up to you, considering some cuts of venison are going for up to £40 a kilo, but that is butchered, you do see where I am coming from, if you think it is to expensive just decline the offer
not in muntie teritory so never had the chance of one, roe fallow and red are my target species, and most of it goes to family and gratefull friends,,,,, and my doctors love venison so I will never have to pay for a doctors reference for my FAC

Cheers
