I am struggling with the cost of supporting my dealer on ancillary purchases such as; filters, 2-cycle oil, plugs, etc. He is an outstanding person and I receive top notch service from him. We have had this relationship for some 15+ years. The only problem, as many of you know, is that the dealer pulls his GP margin on all parts. In no way do I begrudge him making a profit off his clients, because he has a family to support. I just think about going to NAPA for filters, Lowes for plugs, and online parts stores for blades. However, everytime I start to purchase cheaper parts from other sources, I feel as though I am cheating on the guy because he is my friend, and has been instrumental in my success. Do any of you put this much thought into your dealer support?
