There are sites that pull all the information from the flyers for you, and you subscribe, and they tell you what items to buy this week, and which coupons from which papers to use.
There are different ones, the first I looked at had too much name brand / processed/ P&G items listed as the "12 week sale" or "lowest price of the year"... not my type of shopping needs, at all.
The second one, thought was pretty good, I just did not like the subscription price...
