Just my personal preference, but I use plastic accordian style organizers that open wide and are very sturdy. One is blue and the other is red. I bought them on clearance at CVS for about .80 each if I remember correctly.
I look through the ads on Sunday and pull out the ones I want to shop at that week. I use various websites such as afullcup, slickdeals.net, hotcouponworld, etc. to learn about good shopping scenarios, coupon match ups with products, etc. I make a list for each store I plan to shop at, pull out the coupons and attach them to the list (if there's a lot, I put them in an envelope with my list). If the item is on sale, has a store coupon, and a mfg. coupon it can be a shopping bonanza. I try to avoid buying anything if it's not on sale. I have a good stockpile to draw from to avoid having to buy anything last minute. In fact, sometimes I have so much that I donate a lot of products to our church's food shelves, our community's food shelves, and send CARE packages to the troops overseas.
I also belong to and organize a coupon train here on DIS and I sometimes buy coupons from Coupon Clippers if there's something I really want multiples of like when they had the Discover coupon a few months ago. I let friends, coworkers and relatives know if they don't want their coupon inserts from the Sunday paper, they can save them for me. Many people just throw them out with their paper.
HTH a little.
