I've had the same binder for a very, very long time! I have been keeping my eye out for a better one - my favourite part is the little pocket on the inside where I put the coupons that I'll be using - it's not a common thing on binders. It's cheap to start a binder...1st find a decent binder, you don't want the rings popping open etc. Buy some sports card holders at Dollarama to put the coupons in, just fold them if they don't fit. And if you want you can label them into sections. I've had mine in the same order for a long time - not sure why I picked that order but I'm used to it now and I know where everything is. I have sections like snacks, cereal, dairy, shampoo, kitchen, frozen foods etc. It's easy at the store to just flip to the right section to quickly find what you need.
I'm not an "extreme" couponer so a regular size binder works for me...it fits into the grocery bags I always bring to the store anyway so it's no bother to bring it along. I know some people use boxes to organize them now.
I like that this binder also has an inner pocket where I put coupons I find in the store to sort later...Once you start couponing you notice what you need. I started with a cheap binder and an envelope taped to the front of it to hold the day's coupons.
What do you guys use to organize your coupons? What sections do you have? What are the best binders out there?
