We have several digital products for sale on Amazon that we promote on our in-house adult traffic, along with several other merchants products, sex toys, dick pills, creams, etc and yes, they can sell well however, in order to not get banned by Amazon (it took us a while to figure out) you need to filter your adult traffic through to a non-adult domain name/website.
We send our traffic to a 'generic' website that lists the digital and physical products we sell that link directly to Amazon, before we started doing that we had 4 accounts banned because of the 'adult' referral URLs.
Another thing we've started doing that appears to be working well, is linking our exit links to a holding page we designed that it just a page of text links going to specific high selling products, again, its too early to see any significantly noticable results but there has definitely been an increase in revenues over the past couple of months since we started doing this.
Digital eBooks that have a 'sexual' spin to them seem to sell extremely well on adult traffic, in addition to titles that solve issues such as low testosterone, low estrogen and even titles that relate to fitness and diets.
{edit} Just realized this was an old thread bump, info is relevant today though
