Chicken leg quarters often go on sale at ShopRite for $.79, sometimes $.71, per pound. Pork neck bones are usually $1.29 per pound. I buy green tripe from Big Dog Natural for $1.10 per pound, fortunately I can just drive there to pick it up instead of shipping.
I'm feeding 3 GSDs, it doesn't seem to be all that expensive. Besides, I save an incredible amount on vet bills......
