Can you review the postcode of https://www.openstreetmap.org/way/294668651 again? On https://www.coop.se/butiker-erbjudanden/coop/coop-lesjofors/ clicking "Om butiken" I see the address is "Bergslagsgatan 70, 68260 Lesjöfors"
Of course they might have the wrong postcode on their website, that happens, too.
