Hi mums,
Uber cabs is a new cab service in London (they may have them in other cities, not sure yet) Anyway, when you sign up to the service, if you use the code tf2ik in the 'promotions' part when you sign up you'll get £10 completely free, no strings attached. I think you need to enter card details but they don't charge you if you don't use it all - and it's a nice little treat for a bank holiday outing!
Enjoy!
