I don't think too many are close to me around here but the two TSC's I know of in my area are Hazleton and St. Clair. They're both around $14 for a 50# bag of DuMor layer crumbles. What I feed my guys. With fermenting it the bag last me about 6 wks for my 10 chickens. The only other feed stores I know of are Koch's over in Lewistown valley. Was there a few weeks ago and won't go back I don't think. It's changed sooooo much since I was a kid going with my Mom to buy rabbit and chicken feed there. Used to be a nice simple cut and dry feed store. Now it's like a feedstore/Hallmark gift store/PetCo. I won't waste my time going all the way down there. Their prices weren't even that good. Which is understandable with all the money they spend on the "tourist" garbage they sell now.
And then there's Country Junction. Again, prices are a bit more than TSC.
There's supposed to be an Agway around here somewhere but I've never found it. So... I dunno.
