What Ads21 does
Ads21 is an independent weekly-flyer and catalogue directory. Instead of visiting a dozen retailer websites to find out what is on promotion this week, you can browse the current printed-style flyers (often called catalogues, leaflets, prospectus, folletos or Prospekte depending on the country) of local supermarkets, electronics stores, DIY and home stores, fashion, pharmacy and beauty chains in one place, page by page, in your own language.
The site covers 46 countries, each with its own localized edition. You are currently on Katalogi24, our edition for Slovenia, which currently lists 51 retail chains across 7 shopping categories.
Where the flyers come from
Every flyer and catalogue shown on Ads21 is a retailer's own promotional material that the retailer has already published openly to the public, collected from publicly accessible online flyer listings. We do not create, alter or price offers ourselves: the pages you see in our flyer viewer are the retailer's own pages, shown together with the validity dates the retailer published.
All flyers, catalogues, logos and trademarks remain the property of their respective owners. Ads21 is not affiliated with, endorsed by, or acting on behalf of any of the retailers listed. Prices, stock and conditions can change after publication, so always confirm an offer with the retailer before you travel or buy.
How and how often the site is updated
- New flyers are checked for every hour. An automated job compares each country's newly published flyers against what is already on the site and adds only genuinely new ones.
- Store coverage is reviewed daily. Once a day, each country is checked for retail chains that have started publishing flyers, so new stores can be added.
- "Active" and "expired" are decided live. Every time a store page loads, each flyer's end date is compared with today's date. A flyer whose validity period has ended automatically moves to that store's expired archive; nobody has to remember to take it down.
- Empty stores are labelled honestly. If a store has no current flyer, its page says so instead of showing filler, and it is kept out of search-engine indexes until real flyers return.
Our news and shopping guides
Alongside the flyers, each country edition publishes retail news and practical shopping guides (this edition currently has 2 news articles and 2 guides). These pieces are drafted with the help of automated writing tools, working only from information we can stand behind: the real stores, categories and flyers on this site, and publicly reported retail-industry developments. Every article passes an automated quality check before it is published, and any article that fails that check is discarded rather than published in a weakened form. We do not invent prices, quotes, events or people.
How the site is funded
Ads21 is free to use. It may display advertising (including Google AdSense) to cover hosting and running costs. Advertising never decides which retailers or flyers appear on the site, and we are not paid by retailers to list their flyers. See our Privacy Policy for how advertising cookies work and how to opt out.
