Walmart: In-store free sampling events.

Walmart is going full bore with these in-store giveaway events. Here are some more that are happening this weekend:

• Dean Foods Swiss Tea and Fruit
• Atkins Nutritional Bars
• Purina One
• Coty Beyonce Heat Fragrance
• Sun Crystals Keeblers and Tarts

The complete list has even more stuff, including Benefiber, Dove, Degree, Keri Lotion, and more, but you'll have to enter your ZIP code to see when and where these events are taking place near you. If you're a Walmart shopper anyway, you may want to plan your shopping trips so you can swing by for some freebies while you're there.
