We have offered free shipping on all US orders over $50 since we launched the website in 2014. Since then, we have added a number of products - primarily paper - that are expensive to ship. We intend on keeping the free shipping level for the forseeable future, but are increasing the minimum order amount to $75 beginning Monday, June 5th.
This should allow us to better manage shipping costs while keeping ordering from us as simple as possible. All International shipping rates remain the same.
If you have any questions please feel free to email us at firstname.lastname@example.org.
