These guys have a tool that let's you compare the price of any item across all the big stores. So let's say a coupon pops up and you want to try and find a good deal to use it, Just type in the item and it will show you the price at Target, Walmart and all the major drugstores. I just found this last night and have been poking around on it all day.
