Flipp is a free download, and once loaded it will ask your location via postal code. It then takes your postal code and compiles a list of all flyers within the selected radius of your location. You now have access to all available grocery stores flyers (of course some grocers will not have flyers) to browse and find deals.
My first recommendation is while browsing a grocery stores flyer to use the discount slider to highlight items in the flyer that are anywhere from 10-50% off (though this doesn't work for every flyer, as the item needs to quote a discount in the stated price for it to be included in the search).
As a final note, I did end up trying the app for other essential kitchenware, such as a slow cooker and food processor and found some great deals! Every kitchen needs the right tools :)

*Hat tip to my tech savvy wife for finding Flipp, she knows a good app when she sees one.
