I placed my speedy 35 on ebay to be sold. I issued a refund return policy within 7 days and that stipulated authenticity concerns only but apparently it wasn't clear in the listing and now she wants to return it. How do I know that she wont do a switcheroo(lol) on me, and what ways can I protect myself and my buyer rights. I really don't want to issue a return. What do I do people? thanks everybody.
