The difference between the new ShopAlerts service and other similar services, like Facebook Deals, is that it doesn't require the user to check in or perform any other action in order to get the deal. Just being in the vicinity of a participating location or retailer is enough to receive the alert. Messages vary, and may be notifications for sales, special events, new products, or special offers. And, thankfully, the service is limited to just four notifications per week, so there's no worry about becoming inundated with invitations (or messaging fees).

Launch partners include JetBlue, Kmart, HP, and more, with additional providers being added soon. No word yet on when or if AT&T expects to extend the service beyond the initial list of cities, but if other location-based services are any indication, it could go nationwide fast!
