### Comment:
More than likely there wasn't a need to. I'm guessing that it'll cut into profit margins, but it's not like AMZN's one day shipping doesn't cut into theirs? Seems like a double standard 'fear of Amazon' to me.

### REPLY:
Could be.  Amzn may not care if it eliminates competition through forcing them to adapt by slowly eroding profit margins.  Wmt certainly doesn't have AWS to help them either.  AMZN may have found more efficiencies from their own fleet.

### END.
