Confused which card to use for MacBook purchase

As I have multiple cards and I am confused which card to use for MacBook purchase, as my wife's birthday in March and I wanted to gift her MacBook m3

On Flipkart and Amazon I am getting some offers and exchange so it is coming at 90k around with exchange.

As I am using either sbi cb or amz pay icici.

But recently received Amx plat travel. No spends has been done. Anyhow I need to spend 10k in 90days to get the welcome bonus.

With official website I am getting 5x reward point plus it is going around 104000 rs

But without exchange of laptop, I can sell laptop for 5-6k easily. So it would be around 98k.

What you guys suggest?
