So you want to get some free samples and other free stuff?
From About.com
Obtaining free samples and other free stuff can be a hit or miss proposition. You can, however, improve your odds of getting a free offer if you make sure it is from one of the big brand name companies. Sometimes the smaller companies will make an offer that sounds very attractive, but they usually become overwhelmed very quickly and seldom are able to follow through on the free stuff offer.
Brand Name Freebies
Companies like Procter & Gamble or Walmart are a great source of free samples and offers. These companies and many others gladly give away samples in hopes that you like their products and make future purchases. It's a win - win situation all around. You get to try new products without buying them and the companies gain new customers and sell more products.
Free Software
Free software is probably the most plentiful type of freebie you will find on the Internet. Everything from games to heavy duty business applications can be had for free. The biggest problem is determining what free software is useful and avoiding software containing adware and spyware.
