Navarro is a very inexpensive discount pharmacy, you can find anything you are looking for in a regular pharmacy store. I have compared prices of everything including dental flosses, hair gels, toothpastes, painkillers, fever reducers, cotton, chocklate, perfumes etc etc. Everytime Navarros prices beat Target, Publix and Kmart.
There are several stores in miami beach area. There is one just close to the Lehman Causeway, and another on 71st street, very convenient locations.
Well, I believe Navarro is worth shopping. Also, almost all the cashiers are spanish speaking. But they are not very friendly.
