Amazon just launched a new feature for its Associates. Product previews lets you open a small informational window when your visitor is hovering your product link. It works well enough and is easy to incorporate, with nifty little guide-like things added to your Associates page.
Unfortunately this new features relies on you putting a Javascript at the end of every page you use it on, which really doesn’€™t suit Wordpress well. You could probably put it in your footer and have it on all pages, and if you have Amazon ads everywhere then that’€™s fine, but if you like me just want to link every now and then it screws up stuff a bit.
See it in action in my book review (link at the bottom) and check out the FAQ (login required).
