I've developed a "bookstore" on a section on my site, in that I've integrated several search boxes, my Amazon aStore, and an Amazon banner. Will purchases made from searches done through the Amazon search boxes provide me with a referral fee? My associates ID is embedded into the code, but I don't see my associate ID embedded into any of the URLs that result when performing a search. My Amazon bookstore: http://www.worldaffairsboard.com/bookstore.html
Yes, they do. The act of hitting "search" on the Amazon provided search box sets your affiliate cookie for the user.
