I'm thankful to Nykaa for storing important health supplement in the store which makes people like me who works 9to5 jobs with limited time for shopping in real time a bit tedious, so we look to online stores, I hope Nykaa come up with different inventories in the online store for easy access be it cosmetics, health supplement and gadgets but different necessary stuffs and products for loyal customers.
