Heather has started doing coupon classes to teach people how to maximize coupons with sales in order to get the best bang for your buck. Examples of savings that she frequently gets is cereal for free or $0.10/box, free razors, toothpaste, toothbrushes, etc. One of her best trips would have cost $130 at regular price... she got all her groceries for $1.29.
The classes themselves cost absolutely nothing, she wants to share the information. The only cost that you might incur is if you sign up for some newspaper subscriptions (let her explain how it all works though) to get your coupons. Feel free to contact her to set up a class.
