Your are selling 1 free-ride for 5 and 20 free-rides for a total of 30 . These free-rides are valid for 3 months. Wright?
No, one "free ride" (or coupon) is 5. Literally this is a 5 discount for the Uber ride. I sell 20 coupons for 30.
This is lower than a minimal fare for the ride, so you save money anyway.
