If you have infinia or dinner's black card, then you receive 5 reward points for every 150 spent. Value of 1 reward point is 1 rupee. So in short you get 3.3% in terms of reward points. Now if you buy thru smart buy you get 10x reward points. So that comes out to be 33% in terms of reward points.i searched but couldn't find any such offer.
share more about it pls.
