hi there, about 90% of my business is Wholesale... Here's what I do....when it comes to Tarts and even candles minimum is 1lb amount...sooo for example I make 2oz tarts, 2oz into 1lb comes to 8 tarts minimum on one scents same thing with 2 8oz container candle minimum same scent that way you're not figuring out math on making one 8oz candles etc. it makes your life easier....so basically for minimum, make it where it's to what your batch makes. also make it where you want your wholesale minimum to be 150.00 or more or less...then 2nd time reorder can be less. that's where you make it worth your while and still make money. HTH Dani
