grocery price book for Chicago

I am searching for an app where I can keep track of pricing at different stores. While searching for one, I found an article on Lifehacker talking about price books.
There was recommendations for some sites that had them but the recommendation is obviously a localized one since pricing and stores are local. Is anyone familiar with a site that focuses on grocery pricing in Illinois? Naturally, I thought of LTH first, but since the info would be dynamic and specific, I knew at best I could find here a discussion regarding such a site.
Thanks!

The only local site that I'm aware of that ever even mentioned price books is https://jillcataldo.com/topic/price-book-example/ and the thread went nowhere. Her site focuses on couponing and matchups and is about the only local one left.

Hi- I used to post on Jill's site quite a bit until a few years ago when she reformatted her site to make it more user friendly to people who visit it on their phone or tablet. Now it is less user friendly for people like me that mostly visit it and post on their laptop or desktop. She does not get nearly as many posts from readers since she revised the website.

The reason why most of the local couponing websites have bit the dust or regrouped is because there are not as many deals as there used to be. There are not nearly as many food coupons as there used to be, thanks to extreme couponing. The coupons that are available are usually short dated, and so are usually good for a month, or two months if you are lucky. There are still coupons for nonfood items, but they are also short dated, and Proctor and Gamble also quit distributing some of their coupons in the Sunday paper. You now have to print them online, and there is a limit of 2 coupons. You used to be able to get the Sunday papers at Menards and Dollar Tree for $1 too. Menards papers went up to $1.50, and Dollar Tree quit selling them.

Mashupmom actually has a lot more people posting, but she does most of her posts on Facebook now, and not everybody likes Facebook. She also does the great majority of her shopping at Aldi's, and so she quit doing the deals for most of the other stores. She still does Jewel and Aldi's. She also posts a weeks worth of menus based on what is on sale at Aldi's that week. Rachael at mashupmom also posts a lot about Amazon, and reports about her deals at CVS. Right now she is concentrating on Black Friday and Cyber Monday deals at the various stores such as Kohl's, Best Buy and Walmart. Hope this helps, Nancy

Family Dollar now sells the Sunday Tribune for $1.50 too.

It's not worth your while to buy multiple copies of the Sunday paper just for the coupons though, and especially for $1.50. If worse comes to worse, you can buy yourself a cup of coffee at Starbucks on Sunday, and get lots of free coupons. I've found out that since I started using mymixx, I don't have to clip as many coupons anyway.
