How do you as a Vendor add-on to your perceived value?

If value is equal to the benefits of a product divided by it's cost, and if we cannot cut the cost of our product, how do you further extend your value as a Service Provider for the Multifamily Industry? Communication of current events relative to the customer is tops in my book so I hope to be on Multifamily Insiders much more than I have before! My mentor once showed me another prime example of extending perceived value. At a luncheon we noticed they were taking down memorabilia, one being a big plastic Grey Goose Bottle, and he went through his head until a Regional contact came to mind. He gave the waiter a "$5.00 tip" for the bottle they were throwing out, loaded it with clear Christmas lights, poked a hole in the bottom for the outlet and presented it to them on their next meeting. It was not spending $10.00 that yielded the unbreakable bond between them, or the quirky quip he added with it, it was him thinking and acting for others on his own time. How have you went "above and beyond", yet in a simple way?

Showing multifamily management and owners how to make more money, without expending large sums of money. Where the investment was paid for in less than a month and the rest of the time was pure profit. They have been able to take the money and make improvements because they seen an immediate ROI.
