Am I making the most out of my efforts?

Ok, so I am going to take my product to a local business that I have chosen as "My Business of the WeeK" and leave it with them to sample for the week. Along with the use of my product in their business for the week, they will have the opportunity to get the product for free, if they or their customers order $150 dollars worth of my product. Sometimes this has worked (Although not famously. Only resulting in one or two sales), and sometimes no interest at all in my product. Should I keep this up, and be grateful for anything I can get, or try something else? My business and my product are fairly new....maybe things will pick up when word gets out?
