First off, I love you fella. That said, you are going to need to send a deposit equal to your current bid for it to be valid. Address in OP, until then the previous high bid stands.
If I don't win, will you send me back the tx fee that it costs me to send you the deposit, and than cover your tx fee for sending it
And if I do win, can I get discount in the amount of my tx fee for the shipping charges to get this signed unless you want to cover that shipping 🤔
You will lose all the transaction fees in the scenarios you propose. Realize this is because it took you months to close your last deal/auction. I am happy for you to not bid so i am not exposed to the risk of you taking months to sort payment
