Every penny...or dollar counts man. Who's to say he won't find a five dollar COB Brass Supra?
I understand, believe me. I sell vintage drums for a living, and am not getting rich doing it. However, I find that it will really make someone's day, or week even, when rather than being stingy with $5, you just pay what they want, or even throw in an EXTRA $5! Then, when they find that $5 COB supra and want to sell it to a "drum person," chances are they are going to call you! I've had many doors opened to amazing drum deals just because I threw in a little extra for someone that I bought something small from in the past.
