My children have threatened me with an electronic ankle alarm to sound whenever I enter the grocery store, a hardware store, plant nurseries, crafts, books, electronics... get the picture?
Were I to go to any of these stores just to see if there were unadvertised specials - I'm afraid they would have me committed.
I think I related the time my daughter screeched "PUT THAT DOWN" at me from half way across Walmart when she happen to see me at the meat cooler holding a beef tenderloin (on special! only $90.) I dropped it like a hot potato and took off down another aisle - she too, ducked down an aisle, found me and we collapsed in laughter.
