Great value for a quality brew - Dark Roast
Flavor Name: Dark Roast, Size: 24 Count (Pack of 1)
Have been buying a name brand at almost 2x the price. This is rich, bold, and flavorful. We like this dark roast coffee a lot. We will buy it again and continue enjoying these handy pods for our morning coffee.

Great coffee at a great price point.
Flavor Name: Dark Roast, Size: 100 Count (Pack of 1)
I priced these against the pods were were getting from big box and grocery stores and found these were slightly less expensive. Took a chance on these when I didn't have time to run to the store. My coffee connoisseur co-worker said they were the best we've had and our guests have commented on how nice the flavor is. For the price, you can't beat it.

A dark option.
Flavor Name: Dark Roast, Size: 100 Count (Pack of 1)
I decided to try this--I like a robust, rich flavored coffee. The color of Happy Belly Dark is good but the flavor a bit lacking for me.

Remarkable Quality at that Price!
Flavor Name: Dark Roast, Size: 24 Count (Pack of 1)
Look folks, it’s not Barista Prima or Starbucks, but it’s very inexpensive for what you get. It’s strong and tastes pretty good and will wake you up. What more can you ask for?
