My dad used to work for a small family owned steel foundry - every Christmas they would buy every member of staff a turkey.

You could judge the state of their order book by the size of turkey, one year it was too big to go in the oven in one piece, another year my mam had to go out and buy a chicken to roast alongside it.

I used Asda/Wal Mart and they deliver until 9pm, and they give you a 1 hour delivery window. Obviously the evening deliveries get booked up fairly quickly.
