When I got a prescription last time I went to the doctors, I decided to go to Walgreens to get it filled. The main reason was because the location is close to me and conveniently located in the same parking lot as Farmer Jacks so I could get my prescription and go grocery shopping all in one hit.
They took my prescription quickly and within 10 minutes I was ready to go. Since then I've decided to use this as my pharmacy as choice. I really like how they keep in touch via email reminders and you can do a lot of stuff (refilling, setting up auto refills, setting up email reminders when you need refills, etc). I'm a computer person and having this convenience is great. The pharmacy I used to use always insisted on calling when it was ready, which doesn't work for me since I'm not usually home when they call. Walgreens let's me check on my prescription from any computer. They also allow you to access your prescription history which can be great if you have a hard time remembering the exact dosages and such that you need.
I will continue to use Walgreens for all my prescription needs for their convenience and friendly staff!
PROS: They're online! Quick and easy
