Grofer was way better. It's not always that we want our orders to get delivered within 15mins. The first time I ordered from blinkit it was 11pm, I thought it would deliver me next day but I received it at 11:10pm, it was heart wrenching to see the delivery guy at the door step at that time. Hence it should have option for 15mins and should not be mendatory. Also it uses a hell lot of plastic in its packaging. It's harassment for the delivery guys and obviously this model is unsustainable.
