Retailers are pumping still more energy this year into trying to get shoppers to loosen their purse strings early for Christmas with sparkly ornaments, holiday music and special prices. In July.

Target Corp. is entering the game for the first time, with a one-day online sale starting Friday on 500 items from clothing to Blu-ray disc players that's modeled after sales typically held Thanksgiving weekend. And Sears and Toys R Us are dramatically promoting "Christmas in July" online and in the stores based on the success they saw in last year's efforts.
