Go to there https://www.mazuri.com/Home.asp?Products=1&Opening=7 and use the dealer locator to find a feed store near you that carries Mazuri rodent breeder food, they might not have it in stock but they will order it for you.
I just contacted my local agway there say 35 for 50 pound of 6f
Yea I pay $33 from my local tractor supply but with inflation I feel that's not too bad from what the originators of this thread were paying haha. I'm still trying to figure how much I use. Gonna start putting the date I open a bag on the bag so I know exactly how long it lasts. Of course will vary depending how big I grow my feeders i suppose.
