Some time ago Boonex Affiliate commission rates were 20% of a sale. Then, they lowered the Boonex Affiliate Comission to 5% and after some complaining they also reduced the payout to $100. It has remained at 5% for well over a year now.
Recently Boonex announced that they raised commission rates to 15% This is good news however, they have also raised the minimum payout to $300.
Generating $300 in commissions before getting paid can be extremely difficult considering most people buy the $99 permanent Dolphin license. At 15% that is $14.85 per sale, which means you will need 21 sales of that particular license to get paid.
Unless you know or can refer a few people that are going to buy the Prime - $499 license, or the Enterprise - $999 license. I am sure there are a few people out there that do, but I don't know too many that do.
The majority of the affiliate programs I have seen payout at $50 to $100, which is a little more reasonable for most people to acheive.
I really don't even bother promoting it much anymore. You are better off filling your ad space with something that you are more likely to earn and get paid to promote.
