We ship our Moon Calendar posters from within the US.
However, as a very small company in the UK (literally two of us with other jobs and young children to look after) we do not currently stock our wider range in the US as of yet but we're working on it.
We have been blown away by the response we have had in America (thank you all so so much) and can assure you that we will be stocking all kinds of awesomeness for you in 2022.
In fact, if you have any suggestions for the kinds of things you would like to see being made, just let me know at firstname.lastname@example.org
Thank you again :)
