Unfortunately the way Amazon does our item fulfillment, their system won’t allow backorders, and they only take orders when the item is in stock and physically in their warehouse. Sometimes they are very quick to get the item online and available, but other times it takes them up to two weeks to make our items available after I’ve shipped them.
The good news is that a few more starter kits are currently back in stock right now, and I just received more boards from the manufacturer yesterday. I will be trying to get them packaged and back to Amazon as soon as possible.
We’re also hoping to get the accessories like the proto-shield in stock next week too.
