It wouldn't matter. If Amazon didn't want them accessing their servers, they could file suit under the CFAA. They could also allege copyright infringement, since judges have ruled that the temporary copy of a page stored in RAM from which factual non-copyrightable data is extracted (as would be the case on an Amazon product page) constitutes an infringing copy, and trademark infringement and dilution. The existing body of law is very hostile to scrapers. Server access is treated like access to land. The "owner" can kick you off whenever they want.
