Amazon.com (NASDAQ:AMZN) recently licensed 250 seasons of TV shows from Viacom (NASDAQ:VIA) in an effort to beef up its streaming business and add more members to Prime. But Netflix (NASDAQ:NFLX) has proven that it's extremely difficult to make money with streaming, and Amazon adds the cost of two-day shipping as well. 

Fool contributor Travis Hoium thinks this just adds to Amazon's challenges and that margins won't see any improvement in the near term.
