Big-box retailers- the next dinosaurs in an era of renovation.
If Amazon wasn't enough, the "premium" market will cramp big box retail, ironically by winning on COST.
Historically, Walmart decimated small retailers by consolidating and reducing prices. Then enter Amazon, which applied the same principles to the Walmart market.
Finally, we have the rise of specialty stores, which do 'Walmart' better - consolidate products around markets of interest, rather than bringing all of Walmart's offerings to everyone.
--> This reduces the distances customers have to travel to find products of their preference; this also speeds retrieval times in-store, and improves the opportunities for unplanned or discretionary sales.
examples: REI, your walkable neighborhood grocer or winestore, ...etc.
The security and informational advantages to-come offered by Apple Pay will allow marginal sellers to thrive with boosts coming from areas that typically challenge them: discovery and security/transparency [and by implication: confidence].
