For most things I buy, the prices at Winn Dixie are stunningly high. Before they bought out Sweetbay, I had the two competing stores directly across the street from one another (about a mile from my house). Prices on most things were consistently a minimum of 15% higher, and on many things it was far worse. WD's regular price on a large pack of chicken thighs was almost twice as high as Sweetbay's regular price; difference was so great WD's sale price was still 20 cents per pound higher than SB's regular price ($1.79 vs. $1.59), and once a month SB would put them on sale for 99 cents per pound. Now the Sweetbay's closed, but there is a Savalot nearby & I typically buy most basic stuff in there. The Savalot prices are great, but the selection & variety is limited.
There's a Publix under construction about 1/2 mile from the WD; I greatly look forward to its' opening.
