Do you ever buy licenses for shareware software ( definition : software that is available free of charge and often distributed informally for evaluation, after which a fee may be requested for continued use ) ? I only ever bought the license for FRAPS, since I couldn't find a decent alternative at the time. Otherwise, the only shareware apps I use regularly are WinRAR and Malwarebytes. WinRAR can still be used for free after the trial period expires, so I never felt the need to buy it ( and there are good alternatives like 7Zip anyway ). Malwarebytes is also good enough for me as a free app, since I don't need and don't want to pay for real-time protection.
