Who doesn't love a bargain? Sales seem to draw me, kind of like bugs to a light. You just have to be careful not to get zapped. Is it really a bargain to spend money on something you didn't need in the first place and most likely won't use or never would have missed in your life if you hadn't seen the "SALE" sign?
That said, beware these kind of "clearance" signs.
Do you see what I see? CLEARANCE: You could have paid this, but we now we want MORE.
