I have found the deal of the century!!
I used to think that I was getting a good deal when I was paying $7-9 for a 6-10lb bag of assorted bones from a butcher a few towns over. I lost my connection to that place (too far for me to drive just for bones), so I started to search around. The grocery store bones were low quality and they were robbing me blind.
One day I decided to stop by the butcher shop that I drive by on the way to see my horse to see if they offered such a thing. Not only do they have a huge box in the back just for the dogs, but they are DIRT CHEAP. I can take whatever I want for $0.25/lb. Last night I picked up over 10 lbs of bones for under three dollars.
The dogs are currently going to town as I type this.
Gotta love small town butchers!
