It makes sense to me, you purchase all of your materials for the orders that are currently placed, that are due prior to the 11th. So there is a set purchasing and shipping schedule and it allows you to bring in your materials for the standing orders in one fell swoop.
I find it smart in a financial aspect, but difficult since you may get stuck with materials, and having to carry over inventory. All while hoping that someone else *Might* order something using the materials that someone just dropped out of.
I don't like the idea of you not taking orders, but I do understand it.
I still would like for you to create my knife, once I get around to having the spare funds, even if I had to pay extra due to shipping in "My" materials.
