14 of 30 increaser products have enough independent purchase data to price. The rest are in our data but below the threshold we publish at.
Checking a specific increaser price
To check a specific purchase, find the matching product in the table above. If it isn't listed, we don't yet have enough independent purchases of that exact item to publish a figure we'd stand behind.
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 we publish what we have for the last 12 months and say how thin it is. Where a figure rests on very few purchases, a single supplier or a single company, that is noted alongside it — those are 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.
