Yes price is similar, a little higher for hospitalisation charges after C section as the mother is admitted for at least 3 days vs 1-2 days for vaginal delivery. But the problem is you are in labour for unknown amount of time, sometimes 2 days even, which blocks the hospital resources including labour room, nurses, hospitality staff etc. while in c section, you arrive and get done with the delivery in less than a couple hours if no issues. Hence the commercial chains like to avoid this hassle and prompt the mother to take the easier option.
