Flipkart — Delivery fee for Grocery items for Plus members

Hi,
In Flipkart Plus page, it is mentioned that shipping charges will be waived off for grocery orders in case minimum order value specific to the city where the order needs to be delivered is met.

For my city, minimum amount to deliver the item is 600 and 1200 is required for free delivery. So, for plus members shipping fees should be waived off if order amount is more than 600 as per the above statement. But shipping charge is still added even if I add the items for more than 800.

Please clarify the information provided in the Flipkart Plus page. If the information provided in Plus page is incorrect, please correct it.
