I noticed the Airtime Rewards app on the MyO2 app last month, I was a bit sceptical but as it was through MyO2 I trusted it.
I signed up, added a card and without even doing anything I've earned £10 off my bill already from doing my weeks food shop in Waitrose.
I believe it works on pay-as-you go as well as pay monthly, but not sure about business accounts.
Just thought I'd give you guys a heads up if you haven't seen it yet - and you also get a free £3 for being on O2.
Has anyone else had any luck with it?
