This site let's you earn Bitcoins by watching videos and also has an offers section. The Bitcoin is earned in increments of thousands of Satoshis (one video view currently is worth 3000 Satoshis). The offers pay anywhere from 20,000 to 450,000 Satoshis, but I find that I can build up a HUGE amount of Bitcoins just from watching videos (I've done maybe only 2 or 3 offers... the rest of my current balance of 1,384,100 Satoshis came mostly from videos. They use Virool for the video feeds, so there are many video watching opportunities.) They also award 100 Satoshis every hour that you are on the site. https://free.btc.pt/login/?action=register&AFFID=2561 .
