30 Items You Should Never Pay Full Price For

Fact: unless it's something marked with the words "Louis Vuitton" or "American Girl," you probably shouldn't be paying full price for it. It's true. In today's discount-shopping era, there are simply too many easy ways to score a mark down on just about anything.

Is it not on sale? Negotiate. (How? Easy. Step one is to simply and politely ask what "extra promotions" the sales associate can offer—some home improvement stores, in fact, allow cashiers to cut $50 off to close a sale to prevent a customer from defecting to a rival. If that doesn't work, sweeten the deal by offering to pay cash for something and save the store the 3 to 5 percent credit-card transaction fee.)

Now, I'm a firm believer that a little bit of kindness, a big smile, and a lot of savvy will go a long way in saving you loads of money in all of your shopping. But it's doubly—and even triply—true of these 30 items right here. If you're shopping for any of these, go in armed knowing that you're a fool for paying full price.
