For example, you may not do any of the following: use the Service to sell a product or service; use the Service to increase traffic to your Web site for commercial reasons, such as advertising sales; take the results from the Service and reformat and display them, or mirror any portion of the results on your Web site; or use the Services as part of a "meta-search" offering. You also agree that you will not use any robot, spider, other automated device, or manual process to monitor or copy any content from the Service. If you are uncertain whether your intended use of the Service is permissible, please contact us.

Update: And just as a clarification if you're doing this for your own personal use that's fine and I'd consider it to be within the bounds of "fair use"; I've got several HTML::TokeParser scripts which cobble together RSS feeds from sites which don't provide them for my own personal use. Just be aware that what you're doing is forbidden by the letter of the TOS and be prepared to accept the consequences thereof.
