Starting out

If you are looking to get freebies without the surveys than look no more! Here are my favorite sites to watch:
http://www.icravefreebies.com/
http://freebies4mom.com/
http://free-product-samples.blogspot.com/

(Freecycle isn't a sample site but people list items that they don't want anymore on there)
freecycle.org

Also, check out big named stores like Wal-mart (their sample section link listed below):
http://instoresnow.walmart.com/In-Stores-Now-Free-Samples.aspx?povid=cat14503-env172199-module092411-lLinkISNSAMPLES

and Target:

Costco, Sam's Club and Dollar General also give out samples but not as often.

Join http://www.pgeveryday.com/ and they'll occasionally send you a little box of samples like in the image below :)
