You have three bidding options to choose from:
Straight - This is the most common. What ever the bid amount entered, that will be the high bid.
Auto - Also known as Proxy Bidding, you can enter your max bid and our system will bid the next bid increment on your behalf until it reaches you max bid.
Popcorn - Mostly used for high ticket items, any bid placed in the last 5 minuets of the auction will reset the countdown clock to the 5 minute mark and count down again. The item will finally close when no bids are placed in the last 5 minutes.
