When you buy something, you usually do it with a couple of things in mind. The first is typically what you need or want. This is the major reason for any purchase; you need or just want the item. Next, you probably consider price. After all, you don’t want to spend too much money unnecessarily. And those would be the usual criteria. But lets look at another point.
How about holding value? Typically, this is reserved for items like cars. People will often consider the resale value of a car before making a purchase. But why don’t we do this for other things? Most probably never even thought of it.
Let’s take a new TV for example. If you buy a cheap brand, it may work just fine now, but when you want to replace it later on, you may not get much for it on resale. Name brands tend to do much better in this regard, and if you are smart about your shopping, can be bought for only a bit more than the cheaper option.
Computers are another example. Buying one that can be upgraded later is a great way to get more bang for your buck, as making it faster will keep it more useful for longer into the future.
So making smart purchases is really about getting something that is going to have good resale value, or buying things that will stay useful well into the future.
If you are really just looking for the cheapest buy possible, then I would suggest buying used in the first place. Checking out auction sites or pawn shops (http://uspawnjewelry.com/uspawn-4—hollywood) will yield you a number of great, and less expensive buying options.
