I find price to be perceived value, meaning people think different things are worth different amounts. You will have people tell you they are too expensive and you will have people tell you they are priced just right. What matters is that you have covered your cost of materials, your overhead, your labor, and given yourself a little bit of profit. As far as your shipping, it is what it is. You have to make sure it is covered somehow and most people understand that shipping overseas is not cheap. Actually, I'm somewhat surprised it's only $6, I thought it would have been higher.
