When it comes to organizing coupons there is not one right away. But most people use a binder. And sometimes it is a pain trying to get all of the supplies you need.
Enter Amazon  (whom I love). They have everything you need for your binder at prices pretty much the same as you would pay in the store. Plus they have this cool little cutting thing.
Slice Safety Cutter, Green  $4.39 (this thing is AWESOME)
25 Ultra Pro 9 Pocket Page Protectors  $5.89
That can help you get started for $28! And then you can figure out the finer points from there!
