Head to head, product by product
We only count a product when both banners carry it, so a missing line is skipped rather than guessed. RONA is cheaper on 6 of them, Home Depot on 3, with 0 ties.
We left out 2x4x8 SPF stud: one banner's lowest listing is an economy grade board and the other's is not, which is not a fair match.
A price gap of a few percent on a stud is small in dollars and large on a truckload, so look at the gap on the products you actually buy. The brand can differ from one banner to the other: we match the size and the type, and the footnote gives the dates.
