SAVE $$$$$: Do you negotiate when you shop retail?

Do you always ask for a deal?

Do you always try to bargain when you shop, to negotiate for a cheaper price? Over the years I've read a number of articles claiming that you can try to negotiate the price of almost anything. It doesn't matter whether you are at Macy's or some small local boutique, most retailers are willing to negotiate, so goes the argument. 

I have to admit, I don't often think to bargain, but the few times I've tried to bargain, I've gotten a better price almost every single time.
