Startup Idea : Easy and Fast medical needs on demand

Sometimes it's hard to find a drug store or pharmacy that have all the medicine or medical aminities that we need in case of an emergency at home. We do not know all the stores in the area and which stores are open or not. Googling also takes time and not necessarily the store is listed or not. It is good if there is an app that can search nearby or distance pharmacys that sells all the stuff that we need and deliver them to us ASAP
