General rule is whole sale is X2 your cost, retail is X4 your cost, but again I say general rule. Most stores are going to charge X2 there price, so thats what I wholesale them for, I like my price at craftshows to be the same as the stores that carry my line. As far as minimums on orders, thats up to you. I have two stores carrying my candles and I do not have a minimum, but they know to order a few cases when they place a order.
