Is this for the business or for yourself personally ? Morrisons periodically do a Turkey leg/thigh in a pack for about a fiver, its good value for money, the thigh is great slow roasted but the leg has an awful lot of tendons so its better for soup.
It might be a case of buying whatever we can...
Beef, certainly in Steak form has been out of my price range for years. I virtually never eat beef as the decent bits are too expensive and the shit bits ( mince) are, well, shit.
