I was discussing this with someone else...

..but not about lumber. The habit in general for retailers (if they can) to increase prices with futures and then create a different spot when the futures fall.
The gas stations in one of the main areas here are superb at it (and they are convenient enough that they get away with it) - the less convenient stations are faster to fall.
The lumber thing was predictable given that there's no shortage of logs.
Separately, my neighbor is fixing some things on his deck. He purchased all pressure treated parts 15 years ago from home depot. They've changed the style since then. Their decking prices are also (or at least were) unbelievably high, and I guess a while ago, so was lowes.
Two weekends ago, home depot had nothing in stock (he flips houses and has a commercial account there), so he drove to lowes again and whoever is making the spindles and rails is using an identical profile in look and proportion to his originals, and they're half the price that HD had the same day. He doesn't follow commodity markets, and I suggested the likely reason (that lowes was just faster to follow the market down than home depot), but he wants to cancel his HD account over it.
