It depends on where you sell your product. I have just been participating in holiday fairs. Most of my chocolates are bought as gifts - I have done a few large corporate orders. So, my sales come mainly from truffles and chocolate bonbons.
No, I don't make bars, yet.
Truffles , chocolate bars second, but now will try to go to distribute just bars, as I have detected a niche market. What are your expected sales?
