Classic. Can keep referring self and get $10 for my second self and $10 for self. It's a flat $3.50 in places like DC and some flat fee in NYC too for certain areas of Manhattan and maybe Brooklyn. 3 usual restrictions are: device, number, CCs. They don't check numbers really. Used G Voice. Not sure if they allow gift cards yet. And for devices, I can keep changing iPhone mac address, right? #uber #new_york_city #ride_sharing #alternatives #gig_economy #startups #deals #multiply_frugal_deal #pub
