Bux.to is a pay to click site which is very similar to Adbux. You get paid 1 cent per click and 1 cent for every click that your referrals make. You have the option of upgrading your membership which increases your pay per click to 0.0125 per click (both yours and your referrals) and you are guaranteed a minimum of 20 ads a day. This means that you could earn at least 25 cents a day. Membership also includes 5 free referrals and costs $59 for a year. My calculations make out that you would have to click every day for 2/3rds of the year to make back your money. If you have active referrals you could make it back more quickly. You may also get cash bonuses if your referrals purchase referrals themselves.
