I went to Publix on 1/17/20 with the GoodRx app. My prescription on the app came up $39.81. Publix said it keep coming up $54.97. The cashier rang it up several times (so she said). I ended up paying the $54.97. For some reason I decided to call today, 1/20/20. The rep indicated it shows $29.95. She called Publix and called me back indicating they are accepting the $29.95 and will call me with a refund. She did explained that it was at their discretion. Either way, I'm happy!
