Shipping is free within the Contiguous US if your order total is $25 or more. Shipping is $4.99 for orders under $25. This is also true for most products shipped to US States and Territories outside the contiguous US (excluding large/heavy items). During checkout, you can also opt to upgrade your shipping speed/method/carrier if you like. The easiest way to check this is to add the item(s) you want to your online cart, enter your state/zip code and see your costs/choices from the shopping cart page before you check out.
Note that shipping if free if you end up keeping your order. If you return it, then outbound S&H charges will be deducted from the refund amount. Complete details are provided in our "Returns and Exchanges" section of this help page.
