It just depends on what I have.....if it's common, I stick right there with the other vendors, maybe a little lower if I've got a lot to move or a little higher if it is organic and I think I can sell it for a premium.
if it's something no one else has, and particularly if it is something that I bred, that is also organic, and that I have to inform the public about, then I go for a "premium"; and usually after a little conversation and taste testing I can move it.
But people know that Bishop's Homegrown means quality, they also know I'm not poisoning them, and they also know they are welcome to tour the farm 24/7 more or less, so they sort of feel at home with me, even if they have "never seen funny colored sweet corn".
All in all, I keep my prices pretty fair. I live in a pretty economically depressed economy and I keep that in mind, often leaving my prices lower than those around me (exspecially at the height of the season) and those in the big stores, simply because I have more than I can sell, more than I can eat, and more than I am willing to save seeds from, and some folks really have it hard in my county, so I like to give them a bit more for their dollar. However, like I said, if it's rare, organic, or early/late in the season, I get a lot higher price.
