Consumer reports rated it in their top 5 during the last test a couple of years ago, but only the pre-ground stuff. Curiously, the whole bean rated poorly. In a similar test run by Americas Test Kitchen, they gave the whole bean stuff two thumbs down for having too many "quakers" in the bag. Apparently DD does a better job of quaker removal when making the ground stuff than the whole bean.
ATK determined that there was a direct correlation between how many "quakers" were in each sample of coffee and how good it was...fewer quakers, better coffee.
“Quaker” is coffee-industry jargon for an underdeveloped coffee bean that fails to get sorted out before the roasting stage. Lighter in color, and less dense than a regular, mature bean, quakers can wreak havoc on the coffee's flavor profile, imparting a spoiled taste to the brew. In general, the better the coffee did in the taste testing, the fewer quakers beans were in the bag.

Anyhow, if you sign up for the automatic delivery, they give a 20% discount. It costs me about $8.xx to ship four (actual 16oz) pounds. They have specials a couple of times a year for additional discounts. The bags are well enough sealed to still have good aroma and flavor after two months, and we drink about 2lbs a month, so we went with 4lbs every other month automatic.
I think it beats the crap out of most of the supermarket stuff and for a substantially lower price.
