I have downloaded used 1mg app and there are some drawback of using this service 1. Everywhere delivery is not possible within time, means you can’t use it for emergency/regular medicine purchase.2. Some medicines are only supplied to doctors and hospitals directly, you will not get on this app. 3. Delay in prescription upload and action. 4. Given discount are available locally with wholesales marketers that are providing discount more easily for regular medicine customers. Preferred only for metro cities.
