McDonald's: Group-buy offers fake

The fast food chain McDonald's Corp says it has not signed any deals with group-purchase companies following the discovery of discounts for its products being sold on one of China's most popular group-buying websites.

A spokesman for McDonald's Beijing, Weng Xiaomeng, said the company did not authorize any site to introduce offers for its products. "Our operating department will take any follow-up action to deal with this, including legal action," Weng said.

The remarks came after, Gaopeng, a joint venture between Groupon Inc in the US and Tencent Holdings Ltd in China, started offering a discount on McDonald's set meals this month.
