I don't know wheter it is true or not, just saw an article on ezinearticles about it. I'm worried about it because I'm just going to put a product with OTO on the Clickbank marketplace. "Well, it was bound to happen. Because of customers complaining of confusing OTO pages when purchasing from Clickbank, One Time Offers are now banned. If you want to sell an upgrade, you have to do it on the main page with 2 different sales links." http://www.whydowork.com/forums/viewtopic.php?f=12&t=15643 http://ezinearticles.com/?Clickbank-Bans-One-Time-Offers&id=670007
