I was not a bidder on these jerseys but have followed this thread. Despite the fact that one buyer is winning everything, auctions are the fairest way to make it an open market - the auction process allows anybody to bid ANY AMOUNT and have a chance to win something.

If this one buyer seems to have unlimited money supply, the only way to try to challenge that is to bid a jersey up to an unreasonable number and see if he chases it - for example, if Kobe is generally selling at $30g, one bidder needs to be willing to go to $60g if they are that interested in obtaining it. At some point, he will either get tired of way over-spending to continue winning everything, or he will still win items that have no chance of holding their value in the long term, which can't be enticing to most people, even with very deep pockets.

There is no way Meigray/NBA Auctions would limit the bids somebody could place - that would be detrimental to their business.
