Should the supervisor honor this BOGO price?

So there was a bunch of pasta for $3.99 BOGO. But at the cash register, it was $5.29 BOGO. So I challenged it that it was mispriced, and a supervisor admitted it was not 3.99 for that particular type of sauce and for some reason it was stocked in this section (same 24 oz weight, no distinction other than the Bertolli brand).

Then she tried to say the sign did not apply to that particular Bertolli sauce (24 oz, organic marinara). She even tried to take me to another section of the store with a much different label. I dont know that section of the store; i just know what the sign said where I got the bottle.

So she (supervisor) refused to discount it. I felt bad about it, but decided for the moment i needed to be somewhere else, so i had cashier remove the item from the receipt.

So my questions are:

• What is Publix policy about mispricing or wrong signage?

• What about consumer laws about wrong signage / pricing? This Publix is located in Florida, if that matters.

• was the supervisor correct, based on the photos and where the sauce/sign/shelf was located? (items were employee-stocked in wrong place, so she's not obligated to give you discounted price).
