I use Walgreens. The pharmacy for about a year was good about refilling as soon as the insurance would pay (75% of the product used ie. 30 pills, refilled after 21 pills used).

Now this particular Walgreens recently became tight a___ about refilling exactly when I should be out. I went to another Walgreens and they filled a few days early without problems. Then after a few months, the new Walgreens became tight a----. I tried my old Walgreens and there was no problem filling as soon as the insurance would pay. answer-it just depends. I don't think a large chain is better or worse than a mom and pop store.
