I have been using bigbasket.com from many months. It is just a great tool for us who cannot manage to go to market due to office timings. I can order anything right from grocery to fish, chicken and egg. The quality I receive is even better than those available in the ready market. The best thing about big basket is everything is available even soap, diapers and all other necessities for daily life. The delivery is always on time. Never faced any issue regarding delivery.
The packaging is best. One cannot expect such packaging for eggs, fish and all such. The best thing is I can choose time slots for exact delivery. So no tension of being available at home during office hours. The delivery is as per my provided time slots even during night hours. The website has a very good easily usable interface. The customer support is awesome. I never had to return anything. All items are delivered fresh.
