You people are SO lucky!
No matter where, including Big Lots (at least the closest two to me) every place has been out of Cascade with phosphate for a very long time.
Fortunately, I have one unopened box of powder, one opened box of packs, and and unopened box of packs.
I also have some European Finish tablets, and a few precious Somat 9 tablets, but in my water which is hard on the edge of soft, when I use the European tablets, I have to run extra rinses to get rid of the suds. Even so, they clean VERY well, but my water is just not hard enough (!)
