For when there are no deals posted for the company (or Uber for that matter), this is a worthwhile discount for new members.
By joining via a referral, new user gets 25% off their first ride (referee gets 20% off their next ride)
Shofer offers no surge pricing, all cars are company cars (Camrys from memory), choice of male/female driver etc.
just signed up and did a fare estimate, significantly more expensive than Uber.. no thanks
