Hello,
We do sell pork boxes and these are completely standardised, no choices allowed. From half a pig we get 6-7 meat boxes and these will consist of a roasting joint, 2-4 chops and 12 sausages. There are a few left over bits usually and these are what we keep for ourselves. The only choice people get is if they want 2 or 4 chops. We weigh the meat and charge £8 per kilo. I've never had anybody quibble over the price but I guess we live in a fairly affluent area. The prices are certainly much cheaper than say jimmys farm and about an equal price to waitrose quality or tesco finest, neither of which are rare breed or even free range!
We also offer halfs and quarters and the price is reduced a bit (it's a lot less work!)
I say do try and get as much as you can for the area and market you live in.
