sorry it took so long to get back to you....when you list an item right under auto relist you will see show advanced options, click on that and it will let you set the days and credit amount. I hope I explained that, if not go ahead and ask me anything else if I have the answer I will help you
You can't just remove it because you didn't get what you were expecting. You have to state that in your listing prior to the auction. Not after people just started bidding on it
shipping will be free if it gets higher than 500 maybe lower. depends on the final sell price. im kinda new this to this and its my first sale so i wud like to get alot points outta this
