Industry standard wholesale discount percentage for chocolate confections?

I'm a new chocolatier and have an opportunity to sell my chocolate confections wholesale. Is there an industry standard wholesale discount for chocolate confections?

It is up to the retailer, but my experience has been that most double it.

Thanks, Ruth, for confirming my hunch. It seems to be the standard across industries, but I wanted to check and make sure it applied in the chocolate world.
