Ugh! Wait a sec! I don't know what's going on because if you look at the dates of those previous sales, they're from 2014 and 2015.Ah, that makes more sense. Maybe she raised the price temporarily to make sure no one buys while she obtains more stock. I've done that when I've sold something on another site but don't want to end my listing until I'm sure the sale will stick.
Something is very strange.
