Also with these "deals" you often also have to ask yourself:

Are you buying it because it is cheap or are you buying it because you need it? Often people buy stuff they don't need because it is on sale "right now."

Exactly..

A good way to get around this is to keep a "wishlist" of things you actually need and then if there is a sale you can get it.
