Economy shipping takes 1 to 10 business days within the United States and 11 to 20 business days for international. Exact time depends on how far the package must travel. Standard international shipping takes 5 to 10 days.
In the setting up shipping part there is an Economy Shipping (1-10 days) offered where I would plug in the shipping cost figure. No where on the USPS site or eBay Seller site can I find ANY information about this Economy Shipping! I need to know what it is and how it works before I offer it! Help Please.
