Used m-pesa for transaction on Dominos to order pizza, recharged mobile and DTH.
Actually I saw an offer of Rs 50 cashback on transaction of Rs 300 or more pizza, I ordered Rs 410 pizza and within 24Hrs I got my Rs 50 cashback.
It can be accessed with USSD Codes, Website and App of m-pesa.
The best part of it is that you can access it without internet through USSD unlike of Mobikwik/Paytm. It has option to recharge other networks also, has responsible customer care.
