At least in the past (haven't checked in years), the Amazon affiliate program rewarded the affiliate for the next purchase made (within a pretty long time window) after clicking an affiliate link, even if it's not of the product linked; so there's no downside to sending you to an arbitrary, unavailable, irrelevant product as long as you're clicking on links when you're in a shopping mode and likely to make a purchase soon.
