Complete systems and large orders of accessories may take 6-9 weeks for delivery except in special circumstances. Many smaller accessory orders can be delivered within a few days or a couple of weeks, depending on whether the item is in stock in our US office. Consumable supplies are normally in stock and ready to ship the same day. Delivery within the US and Canada normally takes 3 days or less, but precisely how long it takes depends on the mode of shipment. Also, deliveries in large urban areas are often quicker than to less densely populated areas, and deliveries within the US are quicker than to Canada or MExico. Add one to two days for customs clearance into Canada or Mexico.
