Fair point, but it still highlights the issue that bugs me: the reason why they are amazon only is to pay for the site. If there was a business model that supported this aggregation without pay-for-traffic, I bet we'd see a lot more products from a lot more potential sources.

BTW, not saying that no model can exist (subscriptions, whatever) but that most implementations appear to fail out and leave us with affiliate links.

But yeah, I jumped over the main point.
