Wouldn't it be great if you could always know when your favorite products are on sale?

Discount retailer Target is rolling out a new technology that aims to do just that.

"My TargetWeekly" is customized version of its weekly ad. Visitors to the Web site will be able to pick what products they are most interested in and set up custom views of the ad and request alerts when their favorite products are on sale.

They also will be able to view coupons, see top 10 deals, share information via Facebook and Twitter and create their own mobile shopping lists for their next visit in-store or online.

My TargetWeekly can also be found on the Target Facebook fan page, and according to Target, the more guests "love" a product, the smarter the recommendation engine will become.
