Example Input: For those of us with celiac disease this product is a lifesaver and what could be better than getting it at almost half the price of the grocery or health food store! I love McCann's instant oatmeal - all flavors!!! Thanks, Abby

Example Input: Several of the seller's listings indicate 20% Kona blend.....but the delivered product does NOT have this package printing. As a long-time Kona coffee drinker, the contents are more indicative of 10% (or less) Kona coffee. Have ordered twice....and completely disappointed.

Example Input: This is expensive for a 50 lb bag. I looked around for a long time, found that it was the most economical at cos*co, one of the membership stores. It isn't available at the regular warehouses, but at 'cos*co business' store. You don't need to have a business membership card to go there. Price - $ 14.21 for a 25 lb bag, I live in Phoenix, AZ and there is one such store near I-17 and Indian School road. J
