I'm running $2.50/lb all in for Denna's menu. That's here in the greater Seattle area. I get a lot about 1/2 of her stuff at Costco, and the other 1/2 from our big bulk buying group.
I'll chip in on the bone discussion, too... Denna doesn't digest bones very well - they go straight through (luckily they DO go through!). So, she gets about 1/2 her bone requirement from a ground beef with bone product (Happy Tails brand, through our buying group), and the other half I try to find her stuff that she enjoys chomping through. Lamb ribs are a favorite, and whole fish (flash-frozen sardines or mackerel, relatively big 5-6oz fish)
I avoid the cut bone-in pork chops due to the sharp points. She's had one or two, but they make me nervous.
For the turkeys (chicken or pork, too) that go on sale... check the sodium content. You want <100mg of sodium per 4oz serving. Anything "guaranteed juicy" will be over that. Depending on the dog, you might be able to mix in the high-salt stuff with low/no salt stuff... but many dogs react badly to the salty stuff (i.e. cannon-butt).
Some people have great luck cleaning out friend's and stranger's freezers - dogs don't care about freezer burn the way humans do. Freezer burn doesn't effect the nutritional content of the meat much, just the taste and texture - which most dogs don't bother about (unless your DDSK's dogs, anyway!).
