I won a mid-90's Bianchi Veloce on the 'bay, two evenings ago, and I haven't heard boo from the seller, even though I've emailed her twice. I even gave my phone #. I want to drive down to Joliet IL and pick the bike up (and pay her the winning auction price in cash).
How long is reasonable for waiting to hear from a seller? She has a few hundred good ratings, so I would be surprised if she wants to back out on the auction.
