Freebies
Freebies are any offers where you get something for free.
It may be a free CD, free trial membership of a gym, or free samples, but you don't have to pay a penny.
Some of these offers can receive thousands of applications, and from time-to-time the websites close the offers or restrict numbers. All these offers are checked on a regular basis, and should still be active. If they receive heavy demand, they may be slow in sending out the products (if it's mailed to you).
