GetScoreCash is a very well known affiliate program in the niche of big tits. It's has been around for about 30 years and counting being a success with their websites among boob-men.
Scoreland is one of their top websites (digital magazines) since about 1992 and they have a lot of niche big boobs websites and solo big boobs models websites, even Score Classics that remember the good old days of amazing porn stars, this without counting the MILF and mature niche websites.
These sites convert very well and they offer paypal and paxum as payout options making the webmasters lives easier.
Not forgetting that they have RSS and XML feeds of the websites and models directory that helps bloggers and people who know how to work with this kind of codes.
I myself made over 10 blogs of The Score models using these RSS feeds that already come with my track so the sales that come through my links are easily accessible to me.
And now they have a big boobs network that with one sign up the members get access to over 40 sites called BigBoobBundle.
I love this adult affiliate program and I can say that is worth it to sign up as an affiliate if you have boob-men traffic because is one of the best affiliate programs for big boobs to this date. Depending on how much traffic you have you can make pretty decent sales and good money, because I do and I don't have that much traffic yet, I still use free hosting right now (yeah I plan to get paid hosting and a nice domain in the future).
Give it a try, you won't regret it!
