I had a sale today, but there is a bit of a mix up in what color she wants (the listing says that I have 1 set of dark red and 2 sets of light red). Her order came across as two sets of dark red. I've contacted her to see if she would prefer two sets of light or one set of each color. How long do I wait? Obviously, it's not shipping until Monday anyway. If I don't hear back from her, what do you think I should do? Choose which colors myself? Refund the order?
