I just ordered my Christmas Goose and Stuffing from this great online farmshop based in North Lancashire.

Green Pasture Farms - Grass Fed Beef and Lamb, Pastured Pork and Chicken, UK Wide Delivery

They also do a huge range of other stuff and advocate grass finished beef and nitrite-free pork products which is just fantastic. They mention "paleo" so are obviously aware of the demand for good quality produce.
