Hi there, I read about clickbank's terms of use, it says:

---
You will not offer, suggest or imply the availability of any rebates, coupons, tickets, vouchers or similar incentives to induce or encourage the purchase of a Product.
---

Does it allow offering some thing like an ebook as bonus to promote the CB products as an affiliate?

Thanks.

Anyone have any ideas?

That is something you need to ask the author of the product. Some may require that you only use their promo materials and some may permit you to use anything you want PLR/MRR as an incentive. But what Clickbank is stating is that you cannot offer money back or discounts on the product. That is considered an unfair practice because you are essentially taking less of a commission in order to beat your competition and if that practice was allowed, the affiliates would end up having a price war and the commissions would be driven down so far that no one would end up making any money.
