We currently only have the option of selling via Amazon and shipping to US customers only, as it is limited by our Amazon seller account. We hope to one day have other options for all the international requests we’ve gotten, but don’t have any other official options right now. Our current Amazon inventory is also dwindling due to all the shipping and fulfillment issues relate to ordering, stocking, and replenishing the warehouses. So we just ask everyone to be patient until things can return to normal. The Mayfly logger, starter kit, and all the accessories are still being produced and supported by EnviroDIY and the Stroud Water Research Center, they will just appear and disappear from the Amazon system occasionally as their inventory system deals with various logistics issues.
