Ditto, yarddog. I didn’t answer question 3; it didn’t mention the meat department which is where I head first.
If I am in Winn Dixie, I first head to the seafood section. They often have the large fresh shrimp 12-15 to a pound at half price. They are headless but have shells and are not deveined.
Those large ones are the only ones which are really any good.
I then go to the meat section to see if they have any New York Strip, Porterhouse, or Rib eye on special or day old. Their meat is far far better than Wal-Marts.
For staples which are in boxes, bags, jars, etc. Wal-Mart is really a lot cheaper. They are usually cheaper on dairy too. Wal-Mart is typically cheaper on frozen food although Winn-Dixie sometimes has sales which are better.
