Word of advise always use tracking when you mail it is the only proof that you mailed and with all the scammer out there that say that they did not get the items that you mailed. Also start off offering Free shipping till you get a good reputation. I still do all my auctions with Free shipping that way I get the most credits for the listed item. One last thing start off with low value items till you get a few auctions done so that way when you sell the Good stuff that you will get the Maximum credits
Too close to end to add photos You have to have sellers wings to do a GIN and that means that you have completed several successful auctions with a 100% rating and been on Listia for at least a month
If you are going to do free shipping go to edit and change shipping option to free that way everyone will know its free. Listian do not like to pay shipping to new people because so many just flake out and never hear from them again. Good luck
