Edit: First two options are (temporarily?) oos. Still available for $21.13 + FS (with S&S)
Change quantity to 3 and checkout via S&S. = $20.59
When those go oos, next best is the Deep Clean** or Extra Fresh @ $21.13
* Although I couldn't find the Bar size anywhere on the product page. It has the exact same "list price" as these, and those specify 4 oz.
**Looks like the same product but in different packaging.
