Ranked by price. Nothing else. The gap between the cheapest and most expensive verified price is $400.00 (100%). Shipping and duties can narrow it — the retailer's checkout price governs.
Why the gap exists: large price spreads on identical items usually come down to stock position, markdown calendars, or a retailer clearing a colorway. None of that changes what arrives in the box — which is why we compare by exact product, not by lookalike listings.
