The shipment was Prime but arrived in 5 days instead of 2. I love dark french roast coffee, but, this coffee tasted burnt and additionally, the flavor had overtones of trash Indonesian. Not a pleasant experience.

My golden retriever is one of the most picky dogs I've ever met. After experimenting with various types of food, I have found she loves natural balance. What I really like about natural balance is the fact that it has multiple flavors in dry and wet varieties. I mix her dry food with a little wet food and my golden loves it. Furthermore, I do like mixing up the flavors each time as I think the same meal day over day might get a little boring, so I figured why not. I tend to stay away from the fish type though as it smells... Additionally, I started purchasing off Amazon because Petco didn't have the wet food box and only had a couple of cans. I came home and to my surprise realized that I could save $20 each time I bought dog food if I just buy it off Amazon. All in all, I definitely recommend and give my stamp of approval to natural balance dog food. While I have never eaten it, my dog seems to love it.

I have been enjoying the Melitta coffee in the evening. It has a nice smooth taste with none of the burnt coffee bean taste of Starbucks. I used much more coffee than suggested in preparation though. I used 2 tablespoons to eight ounces of water. I like my coffee strong but not bitter and this worked for a very good cup of coffee with half and half added.I will be buying it again.
