Grocery App - Flash foods

Just joined this subreddit TODAY, so I apologize if that is already a hot topic.. The app FlashFoods.. gives me daily lists of stores nearby with lunch meat, chocolate, formula, etc.. all things nearing expiration dates that are going on sale. Usually 50% off or more.

Examples from this morning: Truffle Butter Salmon, best by today, $4 when full price is $8.

London Broil Rst Beef: $4.24, full price is $8.49.

Pudding Cake (cuz poor people deserve treats and nice things): $2.5 when retail is$5.00.

Turkey Wings: 7.93 when FP is $15.87.
