You using analytics? If so you just need to use event tracking on the affiliate links - that way anyone who clicks an aff link isn't seen as a bounce, but a user who has only seen one page but completed an event. I've used it in the past, but don't do it so much recently.
With it you set multiple parameters for category, event (so 'click') and label so you can actually see exactly where the user clicked. Combine it with a database driven system and you can very efficiently get a ton of data about your traffic (I mainly use it with PPC these days for this reason).
Anyway, all you need to do is just stick the following code in your links:
onclick="_gaq.push(['_trackEvent', 'Category', 'Event', 'Label']);"
eg:
onclick="_gaq.push(['_trackEvent', 'reviewpage', 'click', 'somecasino']);"
