Kelkoo Select features hand-picked daily offers, events and experiences, aimed at London shoppers. These include fashion deals from leading designers, tickets to West End premieres, and access to exclusive restaurants in the capital.
Registered members of Kelkoo Select receive offers via email and will be able buy the deal immediately. Some offers require a set number of individuals to opt-in before the deal can go ahead.
Jon Miller, managing director of Kelkoo Select ,said: "Continual growth and development forms part of the business's ongoing strategy, and the launch of Kelkoo Select provides an exciting opportunity for the business to develop a more localised and customer-centric service."
He said Kelkoo would focus on premium customer service, with relevant and tailored offers, to differentiate the site from other group-buying services. It claims all of the products available on the site will be tested and rated by real people before it is sent to its wider customer base.
Kelkoo was launched in 2000 and lists 44 million offers from more than 10,000 online merchants. It claims to attract more than 10 million unique users a month in Europe.
In August last year, Kelkoo appointed Chris Simpson as its first European marketing director.
