7 shopping secrets retailers won't tell you

"It's really hard to conquer the clearance area in some stores because it's actually designed to make you not want to spend time there," says Kay.

Retailers know shoppers want to easily find the size, price and item neatly displayed. So they purposely create the frustration of the poorly marked and poorly organized clearance area to tempt you toward the beautifully displayed and perfectly organized full-price merchandise.

Resist the urge: "Never shop when you are rushed for time," says Kay, "because this leads to making rash decisions." Instead, she advises setting aside time to shop, dig and search for what you truly want, need and can afford from the clearance section.
