I have never sold anything to a pawn shop. What can I expect? Immediate payment? What percentage of worth is it generally? For instance, I own a $550 pair of Chanel sunglasses. How much do you think they'd pay me for them? Is there bargaining involved (or can there be)? What's the best way to approach the shop owner? Do they all generally work the same way, or can I expect to get better offers at various pawn shops? Have you had good experiences working with pawn shops? Will you please share your experiences with me? Thanks!
