Umm...I have not had that experience...?
Costco Foods Smell
I've never had that problem before...maybe try publix or kroger? you won't get as much value for your buck though
Maybe Costco especially targets (no pun intended) you, evaluating your every movement, deducing where to place the distinctly different food just in the right place where you decide to pick it up.
Nowadays there is that awful smell in the meats, like the beef, hotdogs and chicken and egg I get from there... Anyone else and sources PLS?
