Hi @webapalooza,
Thank you for contacting us. We unfortunately do not yet have a restock date on the shipping kits. We are working closely with our vendor and will work on getting those back in stock as soon as we can! Once the ship kit items are re-stocked, you can still use your discount code to place an order for one at the CCG Store! In the meantime, you can use your own shipping materials to ship your books in a similar manner. It is not required for you to use our shipping kits. We thank you so much for your patience as we work on getting the ship kit items re-stocked as soon as we can for you all.
Please let us know if you have any questions.
