We don't take pre-orders or pre-payments of any kind for products. All of our products are sold when they are in stock and available for purchase. We understand there is demand to get in line by pre-paying but it adds a layer of complexity to our business that we want to avoid.
The only exception to this is products made on demand (printed 3D panels) since this is a custom commission product we take payment up front before producing the panels as this is the only method to manufacture them.
