I used to also laugh when garden centers asked a high price for something I wanted. It all depends on what's being sold, and how much your "comfort-zone" is for the item.
Back in 2007 I purchased some "Atreano" trees from a local nursery. The trees were in 3 gallon pots, and were grown well. The trees were between 4-6ft. tall, and each already had set a huge main-crop of figs. I knew that if I didn't screw up, I would be eating figs at the end of the season. The trees were $49.00 each, plus a 20% discount. I bought them, and paid the price. I still have the trees, and they doubled in production. They were a bargain. I didn't have to nurse a small cutting and wait 3-5 years for figs. The trees were old enough to be overwintered in a storage shed. And, my PERSONAL TIME is worth something. I didn't want to grow, wait, and then hope for some twig to produce figs! Now, I let someone else take all the risks, and pay the prices...if, I want the item badly enough. The seller is happy, and, I'm happy. We both win.
