I live just around the corner from Walgreen's. Before living so close, I must admit, I was put off by shopping at pharmacies.
As a rule, pharmacies are generally MUCH more expensive, with much less choice. I have found this to be untrue in the case of Walgreen's.
The staff greets me when I come in, and always asks if I need help. They try to find what I need as quickly as possible when I do not know what I am trying to find.
The store is always clean, the prices are fantastic, and I love how helpful everyone is.
