I actually use 3 different organizers. I'm probably going to have to re-vamp my system soon though, as I'm really getting overstuffed and running out of room!!!! Would love to hear from you guys as to what you do to keep your deals running smoothly and your Q's in order.

2 semi-large accordion style files that I picked up at the Walmart
-- These are for "Food" and "Not Food" basically.
1 small'ish accordion style file that I got at the Office Depot. I call it my Hot Q Holder.
-- This houses the coupons I file for each store I plan to do a deal at (or hope to go to)
-- also has my ECBs, Walgreens Rebate Card, and extra "key tag" cards for the stores. I have one taped inside each store's section.
-- Also in the front I have the "free" coupons, or really HOT Q's that I know I'll use and want to have handy.
-- I keep rebates in there, restaurant Q's, haircut discounts, stuff like that.
I drag them all around with me in a very big Billabong bag that I got at PacSun awhile back. I reckon it looks like a diaper bag, now that I look at it... I originally got it for our vacation to Tucson last February.
I stockpile - meaning I buy stuff that's on sale with a Q. I always go for items that are free or nearly free, and I purchase at least 4 copies of the Sunday paper each week. Sometimes more, if the Q's are really good. My grandmother in Omaha, and my mother in law in Tucson send me their Sunday coupons... because they're awesome, but also because they love me.
I read a lot at slickdeals, and always post there to 'give back'... There are some real deal geniuses there.
I also am always on the lookout for coupons in the stores.
I'm sure there's more to it.. but it's the basics of How I Roll...
