There is no minimum required to place an order. You can order as much product or as little product as you would like. It is useful to keep in mind that the cost-per-pound for freight gets substantially cheaper the more you ship.
Once you enter your zip code, you can try adding and removing items from your cart and check the shipping total. This can help you decide what order size is the most economical to your area.
And remember, with CandleScience, the price we quote in the cart is the price you pay, period!
