Most orders are shipped via USPS in Regional A or B boxes; over 20lb are usually shipped via UPS. We will divide your order and ship in 2 USPS if that option costs less than UPS. We will issue a refund within the website if you are overcharged for shipping. Note: there is also a handling fee of about $4 per box.
Also, if the weight of your desired order totals more than 45lb, please contact us to discuss shipping options and to place your order.
