The answer to your first question is most definitely yes. You can search out deals not only for a specific chain but a specific location of that chain, capturing both local and national promotions. Trader Joes doesn’t take many coupons because it primarily sells it owns branded products, but it does have its own sales that aren’t linked to coupons, which GroceryServer does track.

No grocery shopper is going to run to Trader Joe’s to save 50 cents on cheese, then hop over to Kroger to get a deal on Kraft Mac & Cheese. People shop at one store and go home with their groceries. This has to be super easy.

What would improve this is to build history of what a user’s most likely recipes are. If the user could have their Kroger card account keep track of all their purchases that data could be feed into the grocery saver system and over time the system could find coupons and deals for the user based on what they typically purchase.
