A Business Week article about the store noted that, between 1990 and 2001, the chain quintupled the store number and increased its profits by ten times.[5] Supermarket News estimates that Trader Joe's total sales for 2009 were $8 billion, which gave it a ranking of No. 21 on the list of "SN's Top 75 Retailers for 2011."[3] As of 2010, Trader Joe's sells what Fortune magazine estimated to be $1,750 in merchandise per square foot, more than double the sales generated by Whole Foods Market.[2] (Numbers posted by Fortune magazine are unverified.)

The May 2009 issue of Consumer Reports ranked Trader Joe's the second-best supermarket chain in the nation, after Wegmans.[10] In June 2009 MSN Money released its third annual Customer Service Hall of Fame survey results. Trader Joe's ranks second in customer service.[11] Ethisphere Magazine named Trader Joe's one of the most ethical companies in the United States in 2008, 2009, and 2010.[12][13][14]
