i made an offer on reverb for a couple hundred less than asking, which was already low. I fully expected a counter offer, which I planned on being my reason to keep looking around and just kinda.. didn't plan on anything happening.
you can imagine my dismay (and delight) when the offer was accepted and 20 mins later my bank acct. was mysteriously low on funds and there was a Gibson on its way across the country..
Good times. Now I don't click unless I'm *sure* that I'm sure, but I don't regret that I did! If you aren't sure, then don't worry, as you're not committed; ...can you counter-counter-offer?
Offer them $20 and see what they say. (LOL. don't mind me. )
