1-2-3 Free was the name of a "free stuff" website that used to be hosted at this URL. As of this time, the website is no longer active.
Another good free stuff site that is still in operation is The Free Site. Check it out.
Do be aware, for most free stuff offers, you are giving up personal information in exchange for receiving something for free. There's nothing wrong with this but you should keep it in mind.
There is not as many genuine "free" offers as there once was on the Internet, unfortunately. 1-2-3 Free was online in the late 1990's and there were a large number of great offers available. These days, it is a bit more difficult to find quality.
Nevertheless, you would be surprised what is available out there for a persistent and creative person who is willing to put in the work.
May fortune be with you on your search for free stuff.
