Hey Jennifer, I don’t really know much about MOBE as I haven’t had personal experience myself but in terms of paying for a programs, i’ve had experience with the Six Figure Mentors. They teach people marketing and entrperneurial mindset stuff that I found invaluable. They have a paid tiered membership system that can be promoted on an affiliate basis. What sort of affiliate business are you looking to set up?
It works for me & I've used it myself. It's really hard to promote something you haven't personally used and loved. A good example of this for me would be FlexJobs. I get a lot of questions about this program. If someone asks me where to find something in the dashboard, I can tell them. If they tell me they aren't finding ANY jobs to apply to, I can provide them with a list of steps that may change that. If they ask me if I pay for a membership myself, I can, with 100% honesty, say YES.
For me I would choose a program with Recurring commission. You can build a real passive income. Its the best way to go! One suggestion is contact companies who sell services and ask if you can sell their service for them. Sometimes popular affiliate programs like these have just way too many people trying to sell their service. I personally went to sitecare.ca and asked them if I could sell their service and I couldn’t be happier! So find a service you believe in and go for it!
As an affiliate for Boatbookings, you will receive 20% of their revenue - effectively meaning your commission will be about 4% of any sales from your referrals.  You also receive 10% of any commissions Boatbookings make on repeat customers who were your referrals. They do have a minimum charter value of 3,000 ($/€/£/etc) before commissions are earned.
