Hey now am sharing true exeperince.
Bigbasket.com is very well known site for grocery items and they offering home delivery.
Last month my mother ordered grocery items and selected 90 minutes delivery. Yes we got delivery but in delivery some items are missing immwdeitly we call to custamer care good thing is they recived my complient and solved it within hour.
In this we can order any grocery item with nice price and they giving offers and coupens. They offering two types of delivery mode one is 90min, and other is normal mode. They charging some extra for 90min. Delivery.
I will definatly prefer this to people who don't have time to shop grocery.
