Have you checked out Crowdtap??

UPDATE --Just wanted to give a quick update -- I noticed when I joined that you had to be a level 2 to get a lot of the sample offers -- however in less than 10 minutes I reached level 2.

I have just joined so I do not have any examples to tell you at this point but it does sound a bit like vocal point (which I really like), a little like swagbucks etc.  So, I thought I might as well give them a try.

They say you can get samples of clothes (like jeans etc), gift cards for Amazon among other things
