As the world becomes even more commercialized, an increasing amount of free stuff can be had through discount offers, recycling efforts and Internet loss leaders. Learning where to look for these deals and free samples can save you a significant amount of money on a variety of stuff. Below are the 31 best websites to check out for free stuff, although not in any particular order:

1. Craigslist
While Craigslist has a mixed reputation -- users need to use caution and common sense when interacting with total strangers -- it is also a great source of free stuff. As the phenomenon known as freecycling becomes increasingly popular, Craigslist can be a great resource for finding these offers. Freecycling is based on the idea that many people have used items that have remaining useful life but they are replacing those items anyway. Rather than throwing these items away, the owners offer them to the general public for free.

2. Rollin.NG
Rollin.ng is an online ecommerce strore. They sell all kinds of technology products. While they operate online, they also do business offline at their office located at 29/31 Obafemi Awolowo Way, Awolowo House, Ikeja Lagos. The most interesting fact about rollin.ng is that they give you access to deals on selected products weekly. Just stay glued to their page and enjoy weekly discount.

3. FreeStuff.com
FreeStuff.com gives you access to free samples of common household items ranging from coffee to moisturizer. You can use this site to save money on many items you use or to try out new brands for free.

4. Yerdle
Yerdle describes itself as the "people-powered store." The idea of the site is that the more stuff you give away, the more credits you earn with which to buy other things you might want on Yerdle without having to use cash. While this might seem like it takes more effort than throwing things out, you can get something instead of nothing for items you were going to put in the trash. Using a service like this could be a good option for items that you feel are too valuable to simply give away or throw away but that you're not having success selling.

5. FreeSamples.org
FreeSamples.org is a portal that gives you access to a variety of free product offers for things like household products as well as coupons for products and local restaurants. The offers are updated every day.
