Flipkart made a huge mistake by trying to go mobile-only a while ago and is now mostly a smartphone shop. Hardly anyone I know buys anything other than smartphones (often Flipkart-exclusive) from them. Amazon now has a bigger catalog and better prices too.
Walmart could come along and directly compete in the market by themselves. Wonder why this acquisition is needed at all. There's hardly anything defensible in Flipkart's assets, and this acquisition isn't at a deep discount.
