Like many brands, we switch back and forth between offering low rate, affordable shipping and offering free shipping. When shipping is not free, we do not charge markup over our cost to ship your packages. We never make money on shipping.
You may have noticed that on days we launch products, we generally do not offer free shipping. This is because we are a small brand and shipping is a major expense for us that hurts our ability to grow. If you really don't want to pay for shipping, you can wait and we will almost certainly run a free shipping campaign in the future. However, if you would like to shop with us on a launch day (e.g. to ensure you get your size before it sells out), you will have to pay for shipping.
