Hey, glad to know you've been to our shack! And yes, the last I checked, we might need a higher roof.
With regards to free shipping, I would say it currently works better for us this way where we keep our product prices low with transparency on the shipping cost.
This way, our local customers don't have to pay higher prices which usually comes with free shipping. Plus, shipping cost can vary from country to country as well. However, in future, under the right circumstances, it will definitely be something we will be considering.
Thanks for the encouragement and heads up!
