When the buyer is wil­ling to buy you at rea­so­nable terms. The most cri­tical ele­ment of this is the moti­va­tion of the buyer, and that is out of your cont­rol. The “open to buy” win­dow is crea­ted when their stra­te­gy shows a need they need to address and do it your­self doesn’t real­ly cut it. That’s when they start loo­king, and you need to make sure you show in their radar screen when they do. And that is the part which you CAN cont­rol. Some­ti­mes this hap­pens ear­lier than you would have liked, some­ti­mes later. Timing is not in your hands. Accept it, and act accor­dingly.
