When asked if I felt guilty about charging them to haul them away, I have to say "NO". Anybody who would throw them away deserves it.
Let me get this straight, not only did you get the cabinets, but they paid you to take them. Damn... good show sir, good show. I get jealous of people that have room to take cabinets that they find for a good price, but people who can get paid to take cabinets like those... that's some whole new emotion, like a jealous awe, or envious worship.
Great score, keep us up to date if you do anything great with the cabs or parts.
