Hello, I have an item for sale (a pony saddle) and earlier today I got this offer asking for me to hold the item for $50 more added to the price. I replayed asking for how many days and instantly I got a long paragraph saying that he would send my check and a mover would pick up the item if I would agree with him. I just asked where was he from and no more replays until now. This if my first time selling and new user of the app. Can someone give me an advice? The name of the “person” is Donad Scott, I really think is a spam, could be?
