All the Bricktronics shields still show out of stock. The description for the Bricktronics Shield Kit states " We are currently out-of-stock of the unassembled Bricktronics Shield kits, but we stil have pre-assembled shields available.“, but there is no link to purchase. I have been waiting years for you to get the " Bricktronics Motor Driver” back in stock. Do you still have a valid store? Will you ever get any of these products back in stock?
