Have you ever thrown away the sale circulars that you get in the mail and then realize that, indeed, you DO need to know what is on sale at the local JoAnn Fabric or Office Max?
This site has many of the big store circulars on line. You can also compare prices for specific items. You can also see the ads from your local newspapers.
This is a pretty big endeavor that has cost some big corporation a lot of money.... but is sure makes it easy on us.
Now, I'm not much one for buying at big name stores, but when I do, I hate to find out that the item I just bought at one store was on sale at another store. Yes.... they all say that they will give you the sale price of another store, but you have to KNOW it is on sale at another store. Now you can.
I wish there were more local non-chain stores on this site. Hopefully, the site will grow and there WILL be more small stores listed.
Meanwhile, if you must shop at JCPenny, Target, RiteAid, Walgreen, Ace Hardware, and the like, than at least you can check out all of their sales at once.
This site has portals for most of the major (and not so major - Altoona, PA) cities in the United States. ShopLocal.com
