Worst: Fresh Produce
While we would never advise anybody against consuming healthy produce, we would advise people to simply purchase it elsewhere. Yes, it’s very convenient to just grab a bag of honeycrisp apples or avocado while you’re there anyway, but even with Costco’s lower prices you almost always end up bringing home more produce than you can eat before it begins to turn. And while Costco’s produce quality is certainly good, you can certainly find fresher goods at a farmers market.
