Conflict of interests

I’m trying to do a good tidying of my home. I want to reduce all the clutter possible in the main areas. So that means I want to get rid of any piles of anything and put them out of sight. I’ve just run into a problem though. I have some papers; (coupons, gift certificates, tasks to do) if they are out of sight, they will become out of mind.
How do I organize them so I can’t see them, and yet I can?
