Ok, this isn't a traditional freebie, but it's still pretty cool nonetheless, especially if you spend any time on the Internet. A lot of sites these days are now requiring people to receive “invitations” before they can sign up and actually use the services on the site. Kinda like how Gmail used to be up until a few months ago. This isn't too hard if you know a lot of tech nerds who are always on the Internet to start with, but if that's not the case, then you're out of luck. Well not anymore, as there is a site out there called Invite Share and basically it's just like the name suggests. You sign up, look for an invite code to the website you want to join, and presto! Then, when you have a few extra invites yourself, you can go back to Invite Share and give them away for free, helping to contribute back to the community. It's win-win for everybody!
