The thing about this site is it basically does the work for you. It tells you what paper to buy, what ads you should expect that week, then there is a dashboard with a list of stores and items that you might want all broken down.
IE. Which Ad, Which Coupon, Details of the item, sales price, coupon value, final price, if the coupon can be doubled, if you have a purchase minimum, when the coupon expires, the store you can get the best final price at etc.
The break down is the main reason I want to keep it but like I said so far I have yet to be extreme
