I live near Plaza Italia and most of the time when I go to the Disco at Paraguay and Armenia, the line reaches toward the end of the aisles and it takes 30+ minutes to checkout. At the Carrefour a few blocks away at Scalabrini and Soler, there's hardly ever a line. Aside from the produce being better at Disco (which doesn't matter much to me, because I prefer my verdulería over both), they seem similar to me. What's with the huge crowd at Disco? Is there some huge advantage I don't know about?
