Oops! There's probably some checkout confusion happening here. In almost all cases of a shipping charge showing up unexpectedly, it is caused by the product total dropping below $49 after a discount code is applied. Please note that depending on your browser it may not be obvious at first glance; the "total" you're looking at might be the product cost plus shipping already added, resulting in an amount over $49. You may have to back up a screen or scroll further down to see an itemized receipt.
If you've reviewed your order and still can't make sense of a shipping charge, please reach out to our customer service team here so that we can determine what is causing the issue.
Note that free shipping is only available within the contiguous US states.
