I DO understand why most of this type of an app - a discount shopping tool - would be restrictive in what it offers, e.g; a store selling 'widgets' for one price would not be happy to find another store (in a nearby location) is also featured in WeeklyAdsSales selling 'widgets' for less.
It's a 'no compete' situation, so this means the makers of this type of app must be able to appease it's clients (without stepping on anyone's 'toes') whilst at the same time making the selections offered to the customers - us - be enticing, be useful.
Most apps I've seen of this type, which promise to give you 'discounts, sales, coupons,' etc. are specific to a VERY limited number of stores - and, therefore areas - with which the supposed discounts can be used.
As far as I've seen, there's a much greater latitude in stores, areas (by which I mean both geographically as well as in relation to items offered at a store which sells a broad spectrum of products) with which you CAN find a good discount.
As with anything, there's always room for improvements, and I think the builders of Weekly Ads (seem) to be receptive to ideas & new businesses Weekly Ads could possibly delve into.
I think having Weekly Ads on my iPhone has been helpful, & I'd recommend it to anyone looking to find good prices - for items they actually CAN use.
