# XWUIPriceDropAlert

A product-page widget that lets a shopper set a target price and email so they get notified if the product's price drops to or below that target. It shows the current price, a target-price input pre-filled from the current price, and an email input; a basic truthy check gates submission, and a successful submission flips to a confirmation state.

## Events
