The on-going price war between taxi booking apps has intensified in the run up to Christmas, after London-based black cab app Get Taxi rolled out a new aggressive price strategy. The move, which will see the company charge just £5 to travel up to six miles in designated parts of London - with the app making up the remainder of the fare - follows the news that controversial app Uber has reduced its fares by up to half. The usual fare from Get Taxi costs around £30.
