I see that is going on with "Metro cash & carry" - while they don't cater to simple consumers but small businesses they start to provide tech services to those small businesses not only supplies.

I can imagine part of Target/Walmart business to be like Amazon so they sell their tech to smaller or local players because they would have loads of knowledge in that specific area of ordering and fulfillment.

It is not counter argument as such - but idea that they could become Amazon competitors in some areas and be tech companies.

I'd say AWS is what gives Amazon the "tech" credentials, not Amazon.com which Target and Walmart are working on becoming.
