I love Walmart.com free samples. The signup is relatively easy and painless and you don’t even have to provide an email address! (it’s optional).

The roomie and I don’t usually use the dishwasher (hey we’re asian! haha), but it’s good to run it once in awhile or if you are having a big party and have a lot of dishes to wash. This free sample of Cascade is great since we don’t use it enough to actually buy any ourselves. hehe.
