Ex Input:
This is good coffee, but nothing to write home about.  I like the grind, which is finer than most ground coffee, although I prefer grinding the beans myself.  It has a bold, but not bitter, taste.  Even though I'll stick to Eight O'Clock as my coffee of choice, this one certainly isn't objectionable and is better than most cups you'll get at the diner.  And it's certainly better than Folgers, MH, and other grocery store brands.

My son and daughter-in-law told me about these chips and they purchased a few bags at a store and I will say they are higher in stores then you can get them online on Amazon. They brought me a bag and I was hooked! So I ordered popchips online and they are the "BEST" chips!! There wasn't a flavor I didn't like or that my family didn't like. I am a (chipaholic) and these are better for you and a great tasting chip. I highly recommend these to anyone that can't do without eating chips either with a sandwich, hamburger, or just to munch on midday. You won't be dissapointed.

I love this tea. It helps curb my eating during the day. My Mom and I have given it all friends to try.
