You just are not shopping at the right place. I am in the Edmond area and have no problem finding anything.
For meats I go to Sam's. They have everything, large chucky's, other various roasts, large butts, full packer brisket's, spare and baby ribs, and cheap whole chickens plus about everything else.
I think you have a brand new super target and they choice full packers in 9 - 13 pound sizes for 1.09/pnd. You can't beat that price.
For wood, I'm not sure where you need to go but I go to a place called everything bbq over by quail springs mall and they have all flavors of chips and chunks you could want.
I think we are blessed in Oklahoma to have the meat selection around here from what I read from other folks on the board. I have read of people paying $4/pnd for whole packers that is ridiculous!
