Is there an app or website that will alert you when specific products go on sale or have coupons etc? I have to use specific products because of allergies so stockpiling and couponing is really hit or miss for me. It’s not worth my time to spend an hour slogging through hundreds of sales on things I can’t use. I usually end up with nothing for my time. I would love an app that I could input my limited list of allergy free products and it would contact me when there was a sale in my area and if there were coupons to go with it. Anybody know of something like that?
