Perhaps my reply leaded to a missunderstanding, With a little more, I was talking about the money for your time, as David said, because you can't only charge the pot, soil, wire, tree, and everything you used, because there you are forgeting the tool depreciation, (for being rigurous with the costs), your own "salary" at working on the tree, the water you used to water it, the fertilizer... Man, if we come down to costs, believe me the trees would go over $100...
When I said it depends on the buyer, don't tell me, you wouldn't make a friend a discount, or wouldn't you, just to be FAIR... isn't it true? well, I believe, that if you don't have price labels, on your trees, then you're fixing the price according to the buyer, aren't you?

then why you come to tell me, I'm not being fair... Is just that if you already fixed a price for a tree, then you might keep it... If somebody would come here and ask me for one of my trees, I wouldn't start thinking about costs, only in sentimental stuff, then I would think on a price, but of course, if it's a friend I would ask a little less than to anybody else...
Let me explain it this way, I give classes to some friends, and I know their economical status, so I charge according to that... To some friend I could have charged something like $20 the class, but I charged her $5, but she asked me for nearly 10 classes instead of 1, I got more for more job, but I wouldn't have worked at all, if she wouldn't call me... so I got more, she got more, that's my idea of being fair, I'm sorry if you understood that I was a thief.... I'm far from that... Once I had to reinstall a webpage, and I billed before doing the job _(big mistake) but I had some troubles and I had to take money from my pocket to cover my mistake, I lost, but the costumer won, now they trust me, and like to make business with me, so in the end I won... see that's being fair... or not?
well, sorry I sounded like a thief...
