I haven't had issues with messing up my orders since I got Medicare advantage part d and it got even better after ACA as they included more meds. and could use a major pharmaceutical provider. But back before my surgery when I was on major pain meds I had to get the pain meds from a special pharmacy cause the regular one routinely messed it up and had no meds although they should have known in advance that once a month I'd be filling my pain med. I've never had trouble with psych meds. A couple time the manufacturing place changed. But I got them on time and didn't notice a difference. All in all I'm happy with Walgreens but would not recommend them for pain meds. I'm on line and they send me an email that I can renew my meds, I click yes then I get a notice when they are ready. Since useing their email and on line ordering I've never run out of any meds. I get 90 days of all my meds except ambien and that one they also don't send an email, I have to go online and order it.
