Thought this might be worth a run here before moving somewhere more appropriate as many people here probably have a Tesco Mastercard or even a bmi one.
New promotion running for the next 4 Mondays if you add a Mastercard to Apple Pay and use it for contactless payments on TfL services.
It's valid on all services that take payment using TFL's contactless system so it includes National Rail in the zonal area (plus a few stations just outside it), basically anywhere Oyster and Contactless works right now.
The amount will be refunded in 28 days and has a maximum cap of £27.90 - as daily price capping means most people will never hit that amount it's worth mentioning that this offer also includes the cable car and Southeastern High Speed between St Pancras and Stratford which are not price capped.
So it's valid on all TfL services: bus, tube, Overground, DLR, Tram, TfL Rail, National Rail in the Oyster area, cable car.
Also worth mentioning Tesco only joined Apple Pay last week so if you have one of their Mastercards you can now add it to Apple Pay, that's the only reason I can take advantage of this as my other cards are Visa and Amex.
If you have contactless Mastercard but not Apple Pay it's worth a try (if you are travelling anyway) just in case Mastercard refund all contactless transactions.
