Had to end my items due to unforeseen circumstances. One item had one watcher....should I follow through with letting the watcher know? If I should.....how do I go about that? Thanx so much for the prompt answer to my last question k____5!!!
I unexpectedly have to go interstate for a family emergency....My items (shoes) only started less than 24 hours ago. Can I cancel & relist at a later date?
