when people are paying willing to pay hundreds of dollars for a link from a single page its fairly obvious that the direct traffic it generates is irrlevant.
It's not at all "obvious".
A single link (otherwise known as an AD) from a well chosen single page that sends very well targeted traffic, can indeed be placed because of the direct traffic it generates.
Even for modest cost items that have a high enough markup, a link like that might be a bargain at $100.00 or more, and for high cost, high margin items the cost of the link/ad, might well be considerably more.
How long the link/ad stays in place could seriously affect the price.
