My diswasher needs it, but my local stores don't have it
My dishwasher was designed for powdered detergent and Cascade is the best. Tried for two months to get it locally without success, so I turned to Amazon, the best when-you-can't-find-it-locally place to shop. An Amazon vendor had it, I bought it and it arrived days earlier than expected. Thus, 5 stars for both Cascade and Amazon.
Rating: 5 stars
