Online US daily deals firm Groupon says it has acquired the restaurant reservation company Savored for undisclosed terms.
The move gives Groupon what is described as "a leading provider of reservations at the best restaurants across the United States".
"Savored's platform nicely complements Groupon's efforts in yield management, an area we've pioneered with Groupon Now!" Groupon's Dan Roarty said.
"We look forward to working together to achieve a common goal - making dining out even more fun and affordable for consumers while helping restaurateurs manage inventory and grow their businesses."
The statement said more than 1000 restaurants nationwide had used Savored's platform, which automatically applies up to a 40 per cent discount to customers' bills after sitting them at unused tables.
Chicago-based Groupon has been struggling since a hyped public offering last year.
It posted a sound quarterly profit in August but saw its stock tumble due to a disappointing forecast for the months ahead.
The company made its stock market debut at $US20 per share in November and peaked above $US31 a share. The shares fell another 1.5 per cent Monday to close at $US5.20.
