"This coupon doesn't work?": When a barcode won't scan at checkout, you can now tap the new Help button directly in the barcode view.
Instant replacement: The app instantly suggests alternative coupons from the same retailer that you can select and scan without restarting the checkout process.
Red flags: Coupons that didn't work are automatically flagged with a red flag and marked as "redeemed" for the current card, so they won't slow you down on your next shopping trip.
Manual flagging: Long-press (context menu) a coupon in the list to manually mark it as "Doesn't work" or remove a flag.
Optimized selection: The new selection window for alternatives uses the familiar main list design, including all details on multipliers and expiration dates.
