If you place multiple orders, I'll combine them and refund any shipping overcharges whenever possible (the only foreseeable instance when I won't be able to do this is if your orders are spread apart enough that I've already shipped one or more of them).
Because of the size of this update, I anticipate my shipping turn around time will be longer than usual. I hope to have all orders shipped within 7-10 business days, so if you place additional orders within that timeframe I should have no trouble combining them.
Please note that because I am closing my business, all orders are final. Thanks so much for your understanding!
