L.T.
I have always used coupons. I am not able to boast buying $200 worth of groceries for $5.00 but I am happy with my savings - usually around 30%. Sometimes I will go to drug stores to only buy BOGO items or ones with rebates and I'll save 50% or more.
I have my own system for organizing coupons, though I realy like the Coupon Mom website. If I wasn't so set in my ways I would use the Coupon Mom system with a bit of modification. I've got 2 young kids and can't devote the time right now to switch to her system, though I hope to someday. I do however read her blog and forum every week to learn about special deals, coupons, freebies, rebates, etc. If you are just starting, I would recommend reading her free ebooks as well as the info in the forum for new couponers. You will find tons of ideas from other members and also learn ways that some people have modified her system to be more convenient for them. For example, some people save the cupon inserts from the Sunday paper every week without cutting any coupons and then refer to the inserts when they need them. Other people cut out and file the coupons they would normally use and still save the inserts in case unbeatable deals come up they might be intrested in.
As far as on-line printable coupons, every store has a different policy. O. grocery store I shop at will only take O. internet coupon "per shopping trip". Some won't take them at all. So I don't spend much time looking for and printing internet coupons for groceries. Where I find my greatest deals is with combining sales with coupons (from the Sunday paper), or coupons with rebates, etc. It can really become a fun challenge to see how much you can save. Unfortunately, a lot of people are doing the same thing and it is sometimes hard to get the really good deals that the drug stores run. Our local paper puts out a Sunday edition on Saturday so I buy it then and try to get out early Sunday morning to do my shopping. If you have any questions feel free to send me a message.
