Many stores are also cracking down on the practice of borrowing merchandise, often called "wardrobing" or "closeting." You know, buying a party dress or computer game and then returning it after use.

A common problem for stores is consumers attempting to return merchandise that has been used but not defective. This practice, called "wardrobing," has affected more than half of companies during the past year and can include returns of everything from once-worn dresses to used laptop computers.

Retailers are trying to combat a problem called "wardrobing" — where customers purchase an item, usually apparel, use once and then return it. It's a problem at electronics stores at well. Customers buy a camcorder, for example use it for a week while on vacation, and then return it.
