The discounts offered on this site are just bogus. The discount you get on one item is negated when you add a new item.
They offer discount on one and charge higher price for another. So if you look at tge overall bill, you will be paying much higher than the actual price.
I saw a discount offered for ammis biryani and I tried to place an order through this site. When I calculated the bill amount the total was more than what I expected.
I rechecked the prices on ammis biryani site and guess what? Food panda charges are higher than ammis biryani site. So it will work out cheaper if you directly place an order with them instead of choosing a bogus site like foodpanda.in.
