We work with Epsilon Abacus (registered as Epsilon International UK Ltd), a company that manages the Abacus Alliance on behalf of UK retailers and charities. The participating retailers are active in the clothing, collectables, food & wine, gardening, gadgets & entertainment, health & beauty, household goods, home interiors and travel categories. They share information on what their customers buy. Epsilon Abacus analyses this pooled information to understand consumer's wider buying patterns. From this information, retailers can tailor their communications, sending people suitable offers that should be of interest to them, based on what they like to buy.
