Shipping:
Because shipping costs vary widely, we let eBay calculate the shipping costs based on the buyer’s location.
Normally we use USPS First Class, USPS Ground Advantage, USPS Priority Mail or FedEx depending on the weight of the item.
For international sales, we use the eBay Global Shipping Program. The buyer is responsible for any duty or tariffs and any shipping from the Global Shipping location.
