Markdowns are always on Monday, and things pop back with some regularity. First cut is often a whopping 50%, and second and third cuts often happen too. The shopping cart tracks price drops and popbacks so if you want to stalk something make sure you put it in the cart. You can also have the SAs order you something from another store if it's out of stock in your store. No shipping fee if that is done in store.
This blog is a good resource. They usually list all the new markdowns every Monday.
