E.A.
I buy most of my produce, deli meats and cheeses and fresh meat from the local Farmer Market and always save a ton. Having said that, we have a membership to Costco. I shop at Costco not only for the quality and price (although you really have to know what you'd normally pay at the supermarket, since not everything is cheaper at Costco), but also because of their business practices. They pay a living wage (more than minimum wage) to their workers and aren't associated with other companies that practice predatory pricing (Sam Walton, founder of Wal-Mart, also founded Sam's Club). Costco adheres to a Code of Ethics that recognizes their members, employees, and suppliers (in that order). Their business motto is "Take the High Road and Do What is Right." I believe in shopping at companies I can respect in addition to offering good value and products.
