The three different shipping options for products are Free shipping, Custom Rates, and Flat Rates. We encourage brands to use Free shipping or Flat rates for simplicity.
Please note that for the time being International Shipping only includes shipping to Canada.
Many brands choose to build their shipping costs into the cost of the product so they can offer free shipping. We recommend free shipping whenever possible, as this can significantly reduce the number of your items abandoned in customer carts.
