This is so easy ...... everyone has a Facebook Account right? If not you really should get one - its free.
As an "incentive" to get a Facebook account (and then you can follow me too) Downy has a giveaway for today. They are giving away 500,000 free samples of their new product - unstopable.
Here is the link to their Facebook Page - Downy - that you can like and then get your chance.
