Most orders within the states use expedited shipping by default - USPS First Class, USPS Priority Mail, or DHL expedited. Shipment times for these carriers can range from 2-5 business days depending on the end destination.
Larger orders that generally include 5+ items are not eligible for expedited shipping. Those orders will use DHL economy ground.
Orders outside the USA
All orders outside the USA use DHL international. Shipping times vary from 2 to 6 weeks to arrive depending on the end destination. Most shipments to Canada or the UK take 2-3 weeks though.
