Median $7.59
Based on 15 purchases from 4 vendors, trailing 12 months.
Why there's no product-level breakdown
We track 18 extension tube products, and the figure above covers all of them together. None has enough purchases on its own yet to price separately — 15 purchases spread across 18 products, split again by supplier and by company, leaves each one short of the threshold.
As more invoices come through, the ones that get bought most will cross it and appear here with their own ranges.
How we know this
These figures come from real invoices processed through CostCrunch, not list prices or survey data. Each line is normalised to a price per unit, the top and bottom 1% are excluded as outliers, and a figure is only published once there are at least 10 purchases of that item in the last 12 months. Where a figure rests on a single supplier or a single company we say so, because that is one buyer's experience rather than a market rate.
Check your own invoices against these prices — CostCrunch reads every line item and flags anything above market.
