I count myself lucky on making some major purchases before pricing went nuts. All of those items are now more expensive with long wait times.
It's been interesting to watch the buying habits of some of my neighbors, who are doing major carpentry projects, buying boats, etc. Worst possible time to build anything with store-bought lumber but they seem to have no idea prices are insane or don't mind overpaying. Folks who bought a boat paid full MSRP and then had to wait 6 weeks for their outboard motor to show up. I would have no stomach for those purchases. I think if enough people stuck to their principles and stopped over-paying for stuff, the market would have to come back down to reality.
I need to re-deck my trailer but no darn way I am paying for store-bought treated lumber at current prices. I will probably end up milling my own yellow pine lumber and then soak the heck out of it with used motor oil and hope it lasts long enough to justify the trouble (previous treated lumber deck made it about 8 years).
