According to some numbers this is how the trend goes for ecom.
-Recharge Prepaid Card - 99%
-Buying Movie Tickets - 39.67%
-Utility Bills payment- 37%
-Communication (Aero/Railways) Ticket Purchasing - Rest of %.
Intresting trend to note here is that buying movie tickets is actually stanidng more than paying utility bills. This is inda's data I merged through different source including TRAI.
