It's really my fault for not being careful but I guess it's a funny story.
I decided that the in-house BB was too chunky for me. Put it up for sale and received an offer almost immediately at a price I wasn't so sure about. Buyer was quite persistent and even played the sympathy card, "please I'm sincere but I'm just a student". So I thought, why not and accepted the offer of 3.6.
I once sold a G-Shock when I was in NS, went to the guy's place to deal. Joker took the watch from me (replaced the battery 2 weeks ago), and called me 4 hours later claiming battery finish, ask for refund.
Took it back from him in a more central location, change the battery, put up in Yahoo Auctions again for $20 more, sold in a day. From then on I will never travel to anyone else's place to deal if I'm the seller.
If your price is reasonable (and it seems reasonable), don't need to bow to the buyer, they are getting a good deal, if you still have to travel to make them happy, tell them to go East Coast fly kite.
