With the shopping frenzy of the holidays, there are so many deals out there your head will spin thinking about them. Also, your list of items can get ridiculously long.

Does anyone shop blindly today? Do you ever just walk into a store, browse around and buy something? I guess that still happens, particularly with things like clothes, but with gadgets, electronics and bigger stuff like cars, doing research online before you venture into a store or showroom is critical if you want to make a smart purchase. First, you have to get a better idea of what you want to buy, and then you can think about what deals are available so you can save money.

The good thing is that there’s a ton of helpful information out there on gadgets, electronics and cars. You can browse expert reviews and then look for reactions from consumers. Cast a wide net, and if you’re open minded and flexible, you can end up with amazing deals.

If you think about cars, for example, you can use an online used car price guide to arm yourself with information before walking into a car dealership. Now, like I said, flexibility is important. If you’re dead set on a 60s Mustang or a used Porsche 911 , then obviously you will have less leverage. But if you have a variety of potential cars you want, you’ll do much better.

The same applies to electronics. You might not be able to negotiate in the stores, but you’ll see auctions for products. If you’re not married to one product, you will do better with price.
