O-KAT.RU is an independent catalog aggregator that brings together current promotions from supermarkets, pharmacies, and cosmetics retailers across Russia. Its website helps shoppers browse offers in one place, find discounts on groceries, medicines, fragrances, and beauty products, and plan purchases around available deals. Catalogs are organized by category and retailer, with dedicated sections for brands including Avon, Oriflame, and Faberlic, as well as chains such as Pyaterochka, Magnit, Dixy, Lenta, Auchan, Fix Price, and others.

The site says it updates brochures daily, generally publishing them shortly before promotions begin or on their first day. Visitors can review catalog pages for special offers, gifts with purchases, and promotions such as “1+1,” then make a shopping list before visiting a store. No registration or hidden subscription is required to use the catalog listings. The site also notes that promotional prices and product availability at pharmacies may vary by city or region. O-KAT.RU is not an official website of the retailers or cosmetics brands featured; catalog images are provided for informational purposes.
