What you've been paying your vendors does not have to be the final word on what you continue paying. Ultimately, vendors want to stay in business too, and they're dealing with a tough economy just as you are. Many are often willing to negotiate lower prices rather than lose a regular customer. You certainly won't lose anything by trying, and you may find yourself able to shave several hundred dollars off your monthly operating costs.
So, the above can save you 100's, but wouldn't it be nice if you could realize 1000's of dollars with no upfront fees?!?
