Can we use iFrames for CJ offers or are they in violation of the TOS ? DO any of the affiliate sites allow them these days ?
I do not have the answer to your question, but I would suggest to use php include files instead of iFrames. I do it with CJ links. I change a link once and it gets changed throughout the entire website. (But of course you will have to rename your HTML pages to PHP pages to use include files).
