Moonlighting by a technician is the equivalent of a wholesaler trying to back door a dealer by selling directly to the customer that the dealer is quoting. That is absolutely unethical and I would boycott any wholesaler that used this type of business practice. I had it happen to me so I know where you are coming from. However, I do deal with wholesalers who sell directly to customers but will protect me. By protect me I mean that I would give the wholesaler my customers name and they would not quote that particular customer or they would quote them the same price that I am selling at reserving the profit for me. These wholesalers are far and few between but they are out there. Start your own website with a list of wholesalers that are ethical and those that are not.
