I guess I fell victim to nostalgia and picked up a 12oz bag of ground "Dunkin Donuts" coffee in Target this weekend.
It's indistinguishable from any mass-market ground coffee that I've ever had, but at a net price of $10.66/pound, more expensive. The fine print on the bag says it's made by Proctor & Gamble; maybe it's just re-labeled Folgers.
In retrospect, I suspect that what made their coffee taste so good was the donut that always came with it :-)
[So far as I can tell, there are no Dunkin Donut shops in Minnesota; certainly none in the Twin Cities area]
