Check a building material: price, stock and the same product elsewhere

Paste a product link from Bouwmaat, Hubo, Houtdirect or a partner shop, the EAN number under the barcode, or a few words. AstraNL reads partner shop feeds, refreshed once a day, and store pages live within a daily limit, then shows where the identical product is sold and what it cost at the time shown. Nothing is ordered.
