FYI - Chewy.com has 20% off Bil-Jac dog food. We just ordered two 30 pound bags.
We use the "auto-ship" feature so not sure if that is required. We are constantly adjusting the shipping schedule and my wife saw the 20%. So figured why not order two bags so don't need to worry about it for some time. We just receive a bag in about 2 weeks ago so we should be set for a while. Will throw it in a plastic storage container in the basement.
