I have strong opinions about “that ‘W’ store”. As with all of the big box discount retailers the real reason they have gas stations in the first place is to get you to stop there. They are not so much profit centers as marketing venues and as such they are happy to just break even, if that.
This may be a triple play on Wal-Mart’s part; to be seen as a ‘leader’ in the effort to combat global warming, free promotion of the brand, and to expand the target demographic to those tree-hugging, blue state, liberal nut jobs intellectuals (of which I am one) that currently would not enter the “‘W’ store” unless they were being chased by a rabid mountain lion.
Now, if they were talking about cellulose based ethanol rather than corn/cane based I would be much more impressed, but that’s an entirely different rant. 😉
