Here's my shopper's tip of the week:
If you're going to a specific mall and want to find out before you get there if any of the stores are having sales, Google either the name of the mall or the name of the company that owns it. Then look for a menu for Events or Offers. The mall close to me had several pages of sales that were running at the stores in it. Some other malls will offer deals if you're a AAA member or a member of the mall itself (South Coast Plaza in Costa Mesa, CA). You can also sign up to get emails about special events, new stores opening, etc.
