I try to ship every order within 1–2 business days. Shipping in the U.S. is FREE for 3 or more pairs and a flat rate of $5 for less.
I ship internationally as well, and you will be charged whatever it costs me (you will see the shipping charge at checkout –– the shipping costs depend on what country it is shipping to and the weight). Please note that international shipping times vary, so please be patient! :)
