Here are a few of my favorite freebie sites. They are all updated daily, and I recommend the links to be tried and true. They also have email lists so they will email you all of the daily freebies so you dont have to search the web for them.
Free Samples Network-They have all the freebies, plus links to coupons and rebates.
Free Stuff Times-They also have freebies, coupons, free movie screening listings, and even an app for your smart phone to check in on when you’re on the go.
Shop 4 Freebies-Again, same as above, freebies, coupons, etc
boddit.com-Personal favorite, not only does it have freebies and coupons added all day, it also has headings for all the best deals going on the web like clothes, toys, etc. It is an aggregator which means it adds the best deals from all other sites and puts it in one convenient place.
