Cannot trade and cannot do GIN...you are a new seller....you have to earn your seller's wings in order to GIN and have to add that before any bids happen. Can't trade or make deals once the auction is open and going. And as long as you keep answering questions and keep active on the auction...you are not going to have any problem getting a nice amount for this auction. But you just have to be patient...and follow through....it's just part of being new....before you know it you will have earned seller's wings and will have all of those other options.
FYI...I checked with the person that had the last transaction..and the reason for the negative feedback is this person never shipped the item...just giving you the facts since this person will not answer the question. I was very interested but wanted to make sure I got the item. You of course can still bid...and if they don't ship the item...you will get a refund...however, it ties up your credits for a couple of weeks....so it is entirely your choice...I myself just want to be an informed bidder.
