They're not really promotions. All those 20% off emails only give you 20% off Lyft's fee, not the whole fare. It saves you a total of maybe $2 on an average ride.
I disagree, my email yesterday said "50% off your next 10 rides. You have 10 rides remaining. Max savings of $6 per ride. Discount applies to the fare, Prime Time charges, Service fee, tolls, and taxes only."
