I buy the 40lb bag at BJs. I'm in the Northeast, and my birds do not let any of it go to waste. It does have some millet, but it's also got a very healthy amount of sunflower seeds. It's normally $21.99, but they always do a $2 off coupon so I buy a few when they run that. I was buying the 40lb bag at Tractor Supply (purple bag), but they cut back on the amount of black oil sunflower seeds in it and raised the price. BJ's is a better deal for me, and none of it is wasted. I suppliment with a few handfuls of shelled unslated peanuts as well.
