They do have pieces that come in bulk. I've seen them on ebay. I wouldn't get those though. I always like to get the 12" ones because my kids can chew them down in no time at all. The other day actually, I noticed Riley chewing but his mouth was closed (it looked like he was chewing gum). I realized it was a small piece of a bully stick. I was trying to fight him to get it out of his mouth and he almost started chocking. I literally put my fingers down his throat and pulled it out. Talk about scary. Just make sure to throw them away when they get too small. I saw bully sticks at Pet People the other day that were 3 feet long. They were only $10. I'm gonna put a couple of those under the tree. My dogs are gonna freak out.
