Ex Input:
I had high hopes when I purchased this produce, shipping was amazingly fast and I've tried it a few times. I don't enjoy the taste, and since I don't sweeten my tea, it wasn't that great, and it did nothing for my sinuses. Will not purchase again but I do recommend the seller.

Ex Output:

The wheat free brownie mix is not to my liking.  I won't be reordering. I'd rather not eat chocolate than to eat these brownies.

Ex Input:
These are great beans for the price. If you live in a big city, however, I'd suggest buying green beans at a local Ethiopian shop or even a community Coop. I also remember a Pea berry out of East Timor that was outstanding, but this Tanzanian Pea berry is comparable to standard beans.
