GfK Hungária’s Consumer Scan reports that 90 percent of households bought some kind of dressing in September 2010-August 2011: 70-70 percent bought mustard and mayonnaise, while ketchup can be found in 60 percent of households. However, the level of cross-usage is not high as from 100 dressing buyers only 44 bought all three categories and 21 only bought one. About 10-10 shoppers bought only mustard or only mayonnaise; 4 people out of 100 bought ketchup only.
