It depends on what you are buying? Sometimes you can spend a lot of money and get disappointed in your purchase.For some things I think that you have to spend a lot of money on like good computers, cars (although I am fine with my car that I bought for 1,600 dollars at a county auction), couches, and beds. Trust me when I say this, cheap beds are cheap for a reason.
There is a big difference between the quality in discount stores and quality in department stores. Also if you go to a discount grocery store, the quality and taste of the food is different than the more expensive stores.
