Hi there - first you must get your shipping address verified. This link will show you how to do that; https://help.listia.com/hc/en-us/sections/200657446-Verification
Second - the only way you can win something before the auction end time is to use Get It Now (GIN). Not all auctions have a GIN option but often people are willing to negotiate one. The best way to do this is by sending them a private email. If the auction already has bids (such as this one) there is no way to offer GIN. GIN can only be added to an auction if no one has bid.
