Where these numbers come from

Every figure on this page is live tracker data, prices checked Oct 24, 2026, the same numbers shown on each product's ALLR page. Landed cost means item price + shipping + import duty + customs brokerage to Canada, converted to CAD; retailers are ranked by that all-in figure, not the sticker price. Read the full methodology. Prices and stock move daily, and the retailer's own checkout is always the final source of truth. This comparison covers price, availability and catalog data only — it makes no claim about fit, comfort or performance.
