So I sold an item on eBay. Winner said she'd pay with a M.O. and mail it to me the next day. This was a week ago today, and I haven't gotten it yet. How long should I wait before contacting the winner to confirm if she mailed the M.O. if I don't get it? I don't want to contact her too soon and annoy her. This is the first time somebody on eBay doesn't pay me using PayPal. Thanks!
