I disagree about the meat. Publix has much better quality chicken and pork, especially their Greenwise brand. Costco chicken is freakishly big, even compared to Tyson or Purdue at Kroger. I used to find weird spots on the chicken breast and thighs I haven’t seen elsewhere. The chicken is tougher as well.
The wild seafood is great. Choice Beef is the same as anywhere and I have no complaints. Prime beef is a great option but I rarely buy it.
