That's one costly order.

Germany's Rocket Internet AG says it is spending 496 million euros ($561 million) to buy a 30 percent stake in Berlin-based online takeaway company Delivery Hero.

The internet company said in a statement Friday that it will also buy Italy's La Nevera Roja and Pizzabo for an undisclosed amount.

It said that the new group, which will also include Rocket's existing foodpanda business, will be the largest online food delivery company in the world outside China by orders.

Rocket raised some 1.4 billion euros with an IPO last year.
