If you love receiving samples in the mail, check out Crowdtap!  This is the first sample set I had received from this company and so far am impressed, especially since these samples are regular sized bottles.  There is not a referral link for Crowdtap to share.  Here is their link to check them out:  http://crowdtap.com/

By joining Crowdtap, you will be able to complete polls, questionnaires, and apply for missions to sample products, like the one I had received.

By completing those items above, you’ll earn points.  Recently I earned enough points and was rewarded with a $5 Amazon gift card.  Not much, but still – it was a nice surprise!  The next level of points is another reward.
