I agree with all the other posters. Start small at a small store. It is VERY easy to get overwhelmed! I started at CVS with razors, toothpaste and toothbrushes, and believe me, I made mistakes on some of those small trips because I was too eager to spend my coupons and not really paying attention to what were the best sales. I would see a sale sign on an item and think to myself, I have a coupon for that and I would get it, not realizing it was not a good sale and I should have waited for something better.
I had the mindset that if I didn't spend that coupon today, it wouldn't be good tomorrow. Wrong!! They are good for several weeks, so sometimes it pays to hold on for a better deal. Learn how to make ECBS at CVS, RR at Wags, and UPs at RA work for you. This site is a wealth of information. Spend as much time on here as possible to see what deals are happening now and what will be happening in the future. Beleive me, if there is a free or nearly free deal to be found, someone will post it on here!!!
