Bux.to is a PTC (Paid To Click) site. Basically, you just click on the ads to make money. You also refer people to the site so you can earn more. I like bux.to because it's easy and not that time consuming(compared to surveys). I made $ 0.44 from clicking ads for 2 days - not bad. If it continues that way, that's an extra $12 a month.
