I don't know about "better than Starbucks" but when I was staying in Lafayette, Louisiana, for a few weeks I started drinking Mello Joy coffee from the grocery. This was in my pre-elitist days. Mello Joy was a noticeable improvement over any other can-brand I had tried.
Mello Joy is a regional brand. There are a couple of Mello Joy cafes in Lafayette, too. Pretty good for lunch. The hotshot young Cajun band, the Lost Bayou Ramblers, put out a disc as the Mello Joy Boys in the spirit of old radio shows.
If I were in a position to be drinking sub $4 grocery coffee I would look for Mello Joy.
