Worked purchasing examples use hypothetical quantities and prices to explain unit conversion and scope. They are not live quotes or promises of availability.

Price research: sources, limitations and update method
A rate reviewed today but labeled “June 2026” stays a June 2026 published rate. The review date tells you when the source was checked, not when the supplier changed its price.
Yield, freight and quantity breaks: find the true purchase cost
A hypothetical 200 SF finished requirement at 85% usable yield needs about 235.3 SF of input coverage. Add-on waste of 15% would instead give 230 SF. Keep the basis explicit and round to purchasable boards only after reviewing lengths.
Timber, log and lumber futures prices: three different markets
A hypothetical log report lists $800/MBF under a named log scale. That is not evidence that retail dry lumber should sell for $0.80/BF: recovery, processing, quality distribution and selling costs intervene.
What should be checked?
Identify stumpage, delivered log or lumber.
Keep region and report period visible.
Name the log scale and grade.
Separate forecasts from observations.
Use matching supplier quotes for buying decisions.
Rough, S2S, S3S and S4S prices: drying and milling costs
Hypothetical rough stock costs $500 plus $150 machining and $100 extra handling. Comparable finished stock costs $700 delivered. The rough option totals $750 before considering any additional yield loss.
What should be checked?
Confirm drying condition and moisture requirement.
