James Robertson writes about changing business models of retailers, etc.
Fuel prices are definitely a short-term issue. Moreover, on-line vendors have even more opportunities to take advantage of distribution patterns. WallMart manages their supply chain for their stores on-line. Vendors who do not require a storefront near their customers can optimize their supply chain as far down the distribution chain granularity as they desire. And they can outsource as much of the distribution as they desire.
I am continually surprised at how invisible WallMart is at least to this customer's eyes in building their on-line shopping capabilities. I see Amazon as WallMart's greatest competitor. I still say WallMart should buy Yahoo.
