Up until Monday this app has been very useful in refilling Rxs & clipping coupons. But I set up an appt thru the app to get my covid booster. It allowed me to do the paperwork ahead of time on the app but when I had 1 more question to go, it wouldn't let me complete the work. Tried 2 times & just decided oh well I'll do the paperwork in the store. Got there & they were OUT of the vaccines. So CALL THE PHARMACY AFTER YOU MAKE YOUR APPT TO CONFIRM THAT THEY ACTUALLY HAVE THE VACCINE THERE. SUCKS
