If you have not been advised yet; two units have been repaired and calibrated. The 3rd will likely be done early next week of all goes well. I assume you would like a partial shipment?
It would be my advice to add $60 x 3 ($180) to your order allowing us to ship each in a premium 3 wall custom box. With units of this value (total replacement > 120K) and being fragile it will be a small cost to protect your ultimate goal of delivering these units with no damage due to shipping.
Please also inform us as to how much insurance you would like on each of the three packages.
You can pay the $180 via Credit Card and we would invoice this separately. As an aside you can reuse these custom-boxes at a later date.
May I have your permission to send a CC invoice for $180. Again I strongly advised as the packaging you used is not adequate for repaired and calibrated items of this value. Thank you for your consideration.
