Those are some great looking pies!
Its impressive that you can get an exclusive audience for your pies --- hope that continues for you!
From an outsider's view, from a different market altogether I think that you could easily have sold the same number of pizzas and made another $1,000 for your efforts by simply charging more. They look that good.
But maybe you are limited in your ability to do that, and I would understand 100%
But I would gladly pay $10 for the cheese and $13 for the specialty pies and think I was cheating you out of your hard-earned money!
