I'm a huge fan of CVS Pharmacy. I'll start by saying this convenient location is right off Thunderbird & 99th in the heart of Sun City. Very convenient, easy parking lot access and plenty of ample parking.
This store location is extremely clean as are the restrooms. People often joke about this location being overrun with seniors partly due to its location, but during the toasty summer months (like today), I was in and out of there in no time. Everything is well-marked, laid out quite well and very easy to find.
I will say that CVS Pharmacy can be pricey. There's absolutely no doubt about that so I would recommend checking the weekly sales advertisement AND make sure you sign up for their e-mail solicitation. I know. I know you probably already subscribe to thousands of other newsletters, but the CVS subscription via e-mail makes it worthwhile. In fact, the ONLY reason why I came here today is because I needed more essentials like toothpaste, body wash and shampoo. BUT to make this trip even better was the fact that I got a coupon for 50% off one regular priced item which I used on my shampoo. The toothpaste and body wash I usually buy were all part of the weekly sales ad this week which means for $10 and some change, I walked out of there with my three essentials in a matter of minutes. As far as I'm concerned, that beats the hassle of fighting your way through a Wal-Mart parking lot. In fact, I was in and out of CVS in the amount of time I would have taken me to get a parking spot and walk to the entrance of a Wal-Mart.
Convenience, time-savings and weekly savings are the reasons why I opt to use CVS for my essentials.
