How to check if you have unique content?

Does everyone here use copyscape....however am I missing something here, it costs 5cents each time you want to check something? thats outrages

If it's a rewrite you can use DupfreePRO. If you want to check an original just to confirm that quoted content etc. isn't showing up, you can upload your content to a free Blogger blog and publish. Take the url and then paste the url into Copyscape for free. I use Dupefree and the the paid Copyscape myself though in order to save time.
