Basically, it is a social networking site that you can receive free product/samples from.
After you sign up,
under My Smile.ly,
there will be the "Offers For You."
These are basically the companies that are offering the free samples. You accept the mission and you can share on Facebook, Twitter, etc and you earn smile.ly's!
I first did this with the Durex Love Box challenge.
You do not need a lot of smilies to get challenges and it is super easy.
This is my stats:
Now, I personally signed up for this site, played around on it for a few minutes, signed up for that challenge, and then forgot about the site.
Then this morning, UPS delivered a package to me and boom, I got my Durex Love Box samples! Inside were 16 tins each with 3 condoms in it. Here is the picture - (There are only 15 pictured cause I gave my roommate one!)
So I pretty much did hardly ANYTHING and I got all of these for free! Pretty awesome!
So if you are interested in getting stuff for free, I def suggest signing up!
