First of all, I'm hungry and your cookies look delicious! I think your prices are fair as long as you are portraying your cookies as a gourmet specialty. You mentioned they are packaged in a white bakery box tied w/ a ribbon. Maybe you could try packaging it up a little more fancily and take pictures so people can see that, too. You could also spruce up your site a bit to make it look more professional. If you want some tips, I'd be glad to help you out on that :)
