"Use my Uber promo code, judithy28ue, and get £10 off your first Uber ride. Redeem it at https://www.uber.com/invite/judithy28ue"
This is literally my first time using such a service. I've heard many great things about it, but never really had the opportunity (or guts) to try. Since I'll be needing a ride for my fambam in London, might as well give it a shot.
Not sure if this code is usable for Uber services outside the UK. Do let me know if it does!
