Auction.com bidding advice

[Vanessa Purwar]

Hi, looking for some insight on auction.com counterbidding. Does anyone know how it works? Do they counterbid right away? or can there be a lull and then they counterbid? Can they bid against themselves (if there was no other bid after their counter can they bid again)? Is there any way at all to tell if it is a real buyer vs. auction.com bidding?  This will be my first auction of any type and although i have a set number I really would not like to get to that number if possible and especially if I will only be bidding against myself!  Any insight would be greatly appreciated! Thanks!
