This is a first-come-first-served thing so it may run out quickly. There are 20,000 samples of Finish Jet-Dry Rinse Agent will be given away in September. 4,000 will be given out each week, so if you miss this week, be sure to check back next week. Go to Finish's Facebook page to get your sample.
They are also having a sweepstakes for 1 of 3 Bosch Dishwashers. You're entered in the sweepstakes when you request a sample. Good luck!
