Quoted from MrBally:Go to The Captain's Auctions site for actual details.
Based on the amusement game and other auctions I've attended, usually there is a 13-20% "buyers premium" added to the hammer price. Cash is King for payment, otherwise, add another 2 or 3% for credit card payments. Don't forget the Morongo Valley sales tax rate of 7.75% unless you are a reseller and can prove it. Some high-dollar auctions (think Barrett-Jackson) will accept a credit letter from your bank allowing you to write a check on the spot based on your assets there.
You usually have a few hours after the auction ends to remove your "winnings". If you bid and win on an early item up for bids, you'll have lots of time to get the stuff out. If you bid on one of the last items, pay and back up the truck. Since this will be an internet and in-person auction, you can the chosen shipping company crate and ship your winnings. Fees may apply....
Also, shipping through Captains is insane, like 1200 or something for one pin. So you gotta be able to arrange your own transport day of sale.
