4-5 x 8 are $15+ right now and hard to get. Huge fires over the years that burnt 100s of miles of fences created huge demand for posts. This is a fence on crown land on our range, the Forest Service supplied materials for 2 km of fence to replace one I built in 1991.What do you pay for treated posts in Canada? (Canadian or US?) Did you buy enough to get the semi load discount?
