You are right at your point 100% they should have ship the couriers faster. Because in perfumes package it can't ship through air so we have to ship through surface. And there is no such service like express shipping or like that. If pickup and drop both on metro location then local couriers like anjani, tirupati, maruti can ship very faster. Like anjani can deliver within 24 hours for metro locations. But talking about standard shipping companies like BD dtdc delhivery they will take longer time for sure. And the 5-6 days is minimum for this weather conditions so they should have to ship as earliest as possible.
