Just in case anyone else hadn't noticed - the Uber promotion where you got 5% back on train tickets has recently been reduced to 3%

Still worth having though.
However... I've just discovered that if you join Uber One, you get 10% of your ticket cost back in Uber credits (plus a few other benefits). Uber One is £4.99pm after the first free month.
So even with my relatively low usage of 3 trips per week at £10.25 each I make it a saving of about £12pm, £7 more than the subscription.
Anyone tried this? I'm giving it a go...
