SAN FRANCISCO --Shoppers are encountering a new strategy on the part of retailers on the day after Christmas. Items that don't sell before Christmas are usually discounted the day after. But now analysts say just about everything is being marked down. They say retailers are anxious to generate sales at a time when it's so hard to get people to buy. "They are just starting to realize that the customer while they are starting to shop again they need a real compelling reason to go out and shop," said retail analyst Lori Wachs. But don't be surprised if you run into full priced merchandise. Analysts say retailers want to get you in the door with sales, hoping you won't be able to resist the more expensive items.
