Seems they have this great product and if I promote it, they will give me 50% - 60% as commissions.
I'm sorry, but I thought JV stood for Joint Venture.
All this is, is a request to join your affiliate program for a product I've never even heard of before. How does this help my business and my latest products?
If you want me to join your affiliate program, just ask. Don't try and disguise it as a JV partnership.
