Yes, there is actually an app that will let you see the sales for almost ALL of the stores near you! It will even show you any coupons that can go with the sale. Finally, the grocery savings app I have been waiting for is here!! You can even compare prices between different stores to see which one is the best!
To paint over ANY surface, without sanding, use a product called 'ESP Easy Surface Prep', available at hardware and paint shops. Wipe on, wipe off and paint in 90 minutes. Works well over enamel paint , without having to sand. SAVES HOURS of work. It was recommended to me by a professional painter.
