So the order was delivered before indicated time. Two guys had come. Though there was a minor issue with the order (no surprises there). Instead of akhrot they brought kaju. they took the package back and replaced it with akhrot in 15 minutes.
I guess it is a good option for ordering packaged branded items which has fixed MRP and proper brand. Twitter tell horror stories about the quality of vegetables and fruits. But then if you are going to order Mangoes at 3pm, no shopkeeper is likely to have good ones in stock as they are probably already sold out to customers who come early.
Plan is to check out Big Basket and Peppertap in the coming days.
