Price alerts done right

An alert that fires late, or for a fake drop, trains people to ignore it. Getting alerts right is mostly about restraint.

Price alerts are the quiet engine of a shopping app. Done well, they bring people back at exactly the right moment. Done badly, they become noise the user mutes within a week.

Alert on the effective price

A drop in the sticker price is not always a drop in what you pay. Alerts in Authentic Deal watch the effective price — after coupons and offers — so the notification means something real happened.

Realistic targets beat wishful ones

We nudge people to set a target grounded in the price history. A target below the historical low will simply never fire. Showing the trend at the moment of setting the alert quietly improves the quality of every alert that follows.

  • Track the effective price, not just MRP
  • Guide targets using real history to avoid dead alerts
  • Batch and de-duplicate so one drop is one notification
