What is the cheapest source of lumber on BI?

[maggieblanchett]

Hi y'all, we're going to be building our own house as owner-builders and likely only use contractors for stuff that we can't legally avoid, like electric and plumbing. One thing we would like advice on would be, where do you get your lumber from? We're going to need a source for all our framing lumber and plywood. We're probably going to build our own trusses as well.

We looked where we usually would look, which means the home depot website, but it seems home depot there doesn't carry any lumber!
