Check out the classified section of the board. There are people that offer their scraps and crumbs from time to time and have really good response.
I cut all my scraps down to less than 2" squares and donate them to a group of ladies that make dog beds for our local Humane Society. They use the scraps for stuffing. I feel like I benefit two ways: getting rid of my scraps or crumbs and helping out our furry friends.
