Want a deal?
Ask for one.
You'd be surprised at how many workers don't know the sales going on with their company. Ordering a pizza at a pizza joint? Ask for their specials. Even call on the three or four (or more) in your area to see which one has the best deal.
You could even use this technique with buying cars. Ask for a deal. Don't give the car salesman a price you'd accept, because that is exactly the price they'll get it to. Even if you tell him/her that you can afford a certain monthly dollars amount, they'll twist and turn a loan to fit your budget--for the most part, that is.
