Peter Lynch once said retail investors should "invest in what you know," and it's likely that a lot of readers will have shopped at either Kroger (NYSE: KR) or Costco (NASDAQ: COST) recently. Kroger is the largest pure-play supermarket in the country, operating under brand names Kroger, Ralphs, King Soopers, and others. Meanwhile, Costco is the largest discount wholesale membership club, with 90.3 million members as of its most recent quarter.
Similarly to Lynch, Warren Buffett once quipped, "Whether we're talking about socks or stocks, I like buying quality merchandise when it is marked down." Given the steep price declines in both Kroger and Costco this year, which is the better buy?
