Wow! I don't usually share shopping scores, but I just got 50-ct bully sticks (6") for $50 including shipping on Amazon. They last a long time and my whips are nuts about them. Usually they are crazy expensive so I don't buy them. But in this case they are made in North & South America (no China) and I trust this company (Value Pet Supplies).
The pork twist chewies I used to buy were made in China and although I've NEVER had a problem with them, I wanted to make a change, given the recalls and reports of problems with Chinese-made chewies. Here's the link in case you want to check them out: Value Pet Bully Sticks 6" 50-ct (other quantities available).
