Hey guys,

I want to buy iPhone 11 can anyone suggest where can i get it in cheapest. Few months back Amazon had sale and it was for 47k but now it’s 42k and max 1.5k discount from credit card.

I visited Reliance digital they are charging 55k and giving 5k cashback for hdfc Credit card.

I just want any suggestions to buy it in cheap or should I wait for next sale..
