I come from a region in Europe with a good dozen wineries in every town where all tastings are free and premier wines are cheaper than a supermarket bottle in the US and a glass out at a wine place only cost me about three bucks. So --- I've been wary of wine here, of not so great North Carolina wines, overpriced imported wines from wineries catering only to export business with flashy labels, etc.
Vin Master is the first place I found that made me pretty happy about what I found. He still does get his wines through a chain of distributors and buyers, but I suppose you can't expect much more around here if you're on a budget of about 12 to 30 dollars a bottle. Prices are about the same as or one to two dollars above prices quoted in Wine Enthusiast magazine, so fair enough.
We recently went to one of the Mega Tastings, where you try ca. 25 wines and excellent snacks of good cheeses and meats for 15 dollars. (Hint: bring a designated driver. Really. 25 wines are a lot, even if you only get splashes of each.) If you buy a half case, they discount you the 15 dollars you paid for the tasting (which I appreciate since it brings the business model a little closer to the free tasting culture in Europe). These happen once a month, entirely free smaller tasting happen every Thursday.
As for the type of wines you find here - I think most people can find something here they will like. There are some yuppie wines with happy colorful labels that taste funny and sparkle, but mostly there are some very solid blends and pure wines in a reasonable price range.
