Free delivery for domestic orders. Single bottle orders will be shipped via USPS first class mail. We are upgrading our production facility to meet the increasing surge of demand for our products. We are on a 24-7 schedule and anticipate completing our upgrades by the end of the month. We should be caught up with all orders soon. In the meantime we have several batches in process and are fulfilling orders in date order every week, continuously reducing our fulfillment window till we reach a 2 business day schedule.
