Hm, after reading the posts here... I might give the "free shipping" method a try when I will list one item later in the spring season. I have nothing to lose since I know what my item will bring me by its value - no problem. Beside, this is also one of my last 2 auctions to put up for bids anyway. I don't have anything else to sell here, and think it's time to retire from being a seller.
So, the "free shipping" auction will be my last blast from selling.
