So i tried it and it did increase the bid by 10.00 though i bid 20.00 . it has funny wording when you commit to the bid.( "By clicking the button below, you commit to pay the full 900.00 USD thus buying the item from the seller if you are the winning bidder") I interpret this to mean even if the winning bid is 750.00 i would still pay the full 900.00 at the end of auction.
i looked for more info but their auction information is lacking.

DOG is GOD spelled backwards.
What others think of me is none of my business.
