Seno.dk is a Danish price-tracking service that helps shoppers assess whether a product’s current price is genuinely attractive. It monitors prices at Danish online stores and presents each item’s usual price, lowest recorded price and current price, making it easier to judge a deal using historical data rather than a retailer’s stated “was” price. The site lists more than 20,000 products with enough price history to support an assessment, across 105 categories, and highlights price drops identified each day.

Shoppers can search for a specific product or browse categories such as lighting, cycling, books, home furnishings, electronics, clothing and jewellery. Listings show the retailer, product name, current price, typical price and percentage reduction. Seno.dk says its prices are observed through retailers’ own data feeds; it does not sell products or set their prices. Users can follow links to participating stores, and the service may earn a commission from those referrals without changing the prices displayed. The site also explains its approach to calculating typical prices and evaluating price changes.
