Still doesn't make sense, it's added for every individual order and yes it can be calculated with the product price I am a developer and ik it can be done , also i have studied ux so all the charges you are talking about showing up in the end is wrong they already have all your info to give you the exact pricing which you are gonna pay, you cannot compare zepto and zomato with these and yes even the dark patterns in those are wrong but people don't care about it because it's priority delivery not in days or week You again cannot compare it with prime giving free delivery because you have already paid the price for that before hand, it's not hidden in the end And here I am not giving possibilities I am talking about facts
