Instant Smartphone Sales Alerts

How would you like to shop with your own personal assistant?...sort of.If you own a smartphone you may not have long to wait. In fact, it probably won't be long all before stores will be able to send special sale information directly to your smartphone as you walk through the store. But  for now it's Macy’s blazing the trail. The retail giant is testing a Bluetooth-based system that alerts iPhone users of nearby sale items as they stroll down the aisles.

The system is capable of greeting you as you enter the store as well as offering discounts and recommendations as you shop. There is also an at-home component which allows you to "like" an item in your home and then have your iPhones remind you when you approach the item when you're in the store shopping.
