Not sure if this is a bargain. Saves $. But it is quite useful if you are thinking of ideas to patent or wanting to start a business. Normally you have to pay. This is an easy site I use for work to search and download copies of patents without the annoying registration.

“Download copies of US, European and PCT patent applications as PDF files for FREE!, without user registration or inserted logos”

If you have no idea what a patent is, you should probably find out. There’s also a section on funny or interesting patents.
