Ive gotten several of the Degree Deoderant samples from Walmart's Free sample page: http://walmart.triaddigital.com/Free-Samples.aspx
check it several times a week, items come and go frequently.
Some of the latest to hit my mailbox: Viactiv, Advil PM, Swiffer Duster, Olay Definity, Emergen-C, Oxyclean spot remover, Tide Simple Pleasures detergent, about 20 brands of shampoos/conditioners, lotions, etc. I get tons of presents every week.....free, of course.
