I order mines from the Copelands in Cobb every year.
P.S They are open on Thanksgiving Day if you need to pick it up then. (I believe 12noon to 6pm).
Between buying the bird, the gallons of oil and the injection marinde, you would probably spend $50 and that doesn't include the pot. Copeland's looks like a great deal.
signed, please don't let DH set our yard on fire frying a darn bird for T-giving.
