Yep, got my flu shot last year at the Walgreens near my house. Walk-in clinics are a good alternative to the emergency room. Earlier this year my wife had some slight (we did not know at the time) bleeding and her doc told her to get to an emergency room. Since we knew it wasn't life threatening, we opted to go to the clinic my doc's practice operates, located in the same hospital where her doc told her to go. They had her in before she finished her paperwork, examined her very thoroughly, and gave her a scrip. $5 co-pay, that's all. Our insurance would have had us pay the first $500 if she went to the ER. Also, she could have been there all day waiting. Elderly neighbor went in to ER for broken arm a couple of weeks ago - sat there for 8 hours.
She also recently had her 100,000 mile check-up (colonoscopy). The butthole docs (pun intended) prescribed her a name brand cleanser that cost $158 and not covered by insurance. Pharmacists recommended another brand that has same ingredients, and faxed the docs to change it - insurance covered it 100%.
Lot of value in the pharmacy.
