Clickbank Advertising 2 Questions

1) Am I allowed to iFrame the Clickbank product's landing page, or is it better to cloak the url...........I'm looking for the best way to make sure I will get credited with the sale?

2) Whats with these Clickbank product video landing pages with no order button, the only option is to watch the movie until the end it's freakin annoying...... What's the point, they can't even order the product right away if they wanted to?

1) iFrame is not allowed

2) Each vendor has different landing pages available that you can link to..
