Any way of knowing where the sale came from on your AVS sites?

I've wanted this information for a long time too. But since you don't control the AVS's join form, I can't see a way that tracking sales would be possible. The AVS would know where the join form clicks are coming from but I don't know of any AVS that does this for their webmaster. A lot of paysite sponsors do provide this information to their affiliates though.

exactly, most paysite sponsors give you the exact link to where the sale came from.
This information is so important as an affiliate. It tells me which model is selling, which text/solors/layout work best etc
