Apollo Pharmacy is a big brand in all pharmacy division and it has good customer service and those who was has account in it they will have good discount offers. Very rare u find unavailability of product there as they maintain almost every range in medicines including diabetec, cardiac, analgesic, antihypertensives and other OTC products and all the products are standard and they maintain the best quality. Once I had an issue with an outlet and they resolved the issue in a single day after raising a complaint. I liked their customer support. Good!
