Chew.com has a promo on American Journey Dog Food where the first bag is 50% off. Also, have a sale on their Chicken and Brown rice where each bag is $14.99 (28lbs each up to 3 bags). Since my dogs eat the Salmon and Sweet Potato (24lbs), that's the bag I chose to get 50% off on.
Auto-ship gets you and extra 10% off (cancel anytime)
Free shipping on orders over $49
1. Add bag you want 50% off on (ie. Salmon and brown rice):
2. Add 3 bags of Chicken and Brown Rice:
3. Select Auto-Ship for 10% off. FS should be added automatically.
You can prob get a cheaper total if you play with the bag you get 50% off on, I chose this one because its what they currently eat and can ween them off of it for the chicken and rice.
