Good luck to y'all. Having set prices for items is difficult at best, but I can really dig what Eagle has to say about customer "politics". Not knowing the "ropes" on something like this may be some cause for panic in those touchy situations when some "hotshot" customer calls your bluff on an expensive item, but I'm sure after a few of those experiences you get your "sea legs". I do side work from time to time, and I often feel like I'm the "King of the $10,000.00 light bulb, and the Queen of the $.25 service".
