This would be Folgers coffee. You may have noticed that the container size has gotten smaller. This morning I happened to see Folgers coffee at a big box store, and they had plenty of the new, smaller containers. But there were two of the old, larger, containers nestled on the shelf along with the new ones. I bought both of the big ones for the same price the store was charging for the smaller ones, $8.59.
The small one says it contains 24.2 ounces. The larger one says it contains 27.8 ounces. The calculator says the new, small one sold for $0.35 per ounce, and the large one sold for $0.31 per ounce. It's not a huge difference for the occasional shopper, but you know it means a lot of money for Folgers.
Meanwhile, the price of coffee as a commodity is going down. Too bad they couldn't pass the savings along to the consumer.
