How this comparison works

These retailer offers are joined by a checksum-valid barcode. A similar name or model number alone does not create a match.

We rank item prices from low to high. Where a delivery charge is missing, we cannot claim a cheapest delivered total. Taxes, delivery restrictions and checkout promotions should be confirmed with the retailer.

Each retained price carries its source observation date. Withdrawn or explicitly expired offers are excluded. “Reported available” describes the feed observation, not a live checkout check.
